On 12 August, Chelsea suffered a nightmare start to their Premier League title defence, losing 3–2 at home to [[Burnley F.C.|Burnley]], who had only won once away from home in the previous season.

Morata would later add to Chelsea's goal tally with a header in the 40th minute, scoring his second league goal of the season.

On 9 September, Chelsea earned a 2–1 away victory at Leicester City, making it a third Premier League victory in a row. [[N'Golo Kanté]] scored the second goal for ''the Blues'' against his former club. Davide Zappacosta made his debut for Chelsea while Eden Hazard returned from injury, coming on as a substitute.<ref>{{cite web|url=http://www.bbc.com/sport/football/41133348 |title=Leicester City 1-2 Chelsea |date=9 September 2017 |publisher=BBC Sports}}</ref>
On 12 September, Chelsea marked their return to the UEFA Champions League with a 6–0 thrashing of Azerbaijani champions [[Qarabağ FK|Qarabağ]], who made their first ever appearance in Europe's elite competition. Goals from [[Pedro (footballer, born July 1987)|Pedro]], [[César Azpilicueta]], Tiemoué Bakayoko, [[Michy Batshuayi]] as well as a goal from Zappacosta on his first start for Chelsea, and an own goal by Qarabağ player [[Maksim Medvedev]], sent ''the Blues'' to the top of their group after the first round of fixtures.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41216361|title=Chelsea 6–0 Qarabag|publisher=BBC Sport|date=12 September 2017}}</ref>
On 17 September, Chelsea hosted rivals Arsenal at Stamford Bridge, who managed to emerge with a point by drawing 0–0 with ''the Blues''. It was a frustrating match for Chelsea, who created several opportunities to score but could not find a cutting edge against a well-drilled Arsenal side. The game was also marred by David Luiz receiving a red card in the second half for a high tackle on [[Sead Kolašinac]], with the defender set to miss Chelsea's next three matches as a result. His red card amounts to Chelsea's third red card of the season. The result sees ''the Blues'' remaining in third place, three points behind joint leaders Manchester United and Manchester City.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41216718|title=Chelsea 0–0 Arsenal|publisher=BBC Sport|date=17 September 2017}}</ref>
On 20 September, Chelsea hosted [[Nottingham Forest F.C.|Nottingham Forest]] in the third round of the [[2017–18 EFL Cup|EFL Cup]], defeating the Championship club 5–1 to advance to the next round. Amongst the goalscorers was Batshuayi, who completed a hat-trick with a goal in the first half and two further goals in the second half. [[Kenedy (footballer)|Kenedy]] and Charly Musonda also got on the scoresheet, and youngster [[Ethan Ampadu]] made his first senior Chelsea appearance as a second-half substitute.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/41249727|title=Chelsea 5–1 Nottingham Forest|publisher=BBC Sport|date=20 September 2017}}</ref>
On 21 September, the long-protracted transfer saga surrounding exiled striker [[Diego Costa]] came to an end as Chelsea agreed a fee with [[Atlético Madrid]] for his transfer, to be completed in January after the expiry of the Spanish club's transfer ban.<ref>{{Cite news|url=https://www.chelseafc.com/news/latest-news/2017/09/diego-costa-transfer-agreed.html|title=Diego Costa transfer agreed|publisher=Chelsea Football Club Official Site|date=21 September 2017}}</ref> He leaves Chelsea having scored 58 goals in 120 appearances for ''the Blues'', including 20 in the Premier League last season as Chelsea won the title.<ref>{{Cite news|url=https://www.bbc.co.uk/sport/amp/football/41369356|title=Diego Costa: Striker says he will always have 'special affection' for Chelsea|publisher=BBC Sport|date=21 September 2017}}</ref>
On 23 September, Chelsea earned a fourth Premier League victory in five matches after thrashing Stoke City 4–0 away. Álvaro Morata opened the scoring for ''the Blues'', with Pedro adding a second before half-time. Morata completed a hat-trick in the second half, Chelsea's first Premier League hat-trick since 2014, to keep ''the Blues'' in third position and within three points of the two Manchester clubs at the top of the table.<ref>{{Cite news|url=http://www.bbc.com/sport/football/41290319|title=Stoke City 0–4 Chelsea|publisher=BBC Sport|date=23 September 2017}}</ref>
On 27 September, Chelsea beat Atlético Madrid 2–1 away in a Champions League group stage match, making history in the process by becoming the first ever English club to defeat Atlético away from home in a European competition. Chelsea fell behind late in the first half after David Luiz conceded a penalty, which [[Antoine Griezmann]] converted. Morata leveled proceedings early in the second half with a header. The match looked to be finishing as a draw until Michy Batshuayi snatched a winner for Chelsea at the death. The result sees ''the Blues'' go top of Group C, four points ahead of Atlético and Roma after two match.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41379696|title=Atletico Madrid 1–2 Chelsea|publisher=BBC Sport|date=27 September 2017}}</ref>
On 30 September, three days after their Champions League heroics, Chelsea lost 1–0 at Stamford Bridge to league leaders Manchester City in a very poor performance that culminated in Chelsea only having two shots on target in the whole match. The defeat sees the gap between the two sides widen to six points, with Chelsea slipping into fourth.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41370356|title=Chelsea 0–1 Manchester City|publisher=BBC Sport|date=30 September 2017}}</ref>
===October===

On 14 October, in their first league match after the international break, Chelsea fell to a very poor 2–1 away defeat against bottom Premier League side Crystal Palace. The home side scored their first goals and earned their first points of the season after losing their opening seven fixtures without scoring. An own goal from César Azpilicueta opened the scoring early in the first half before Tiémoué Bakayoko leveled proceedings shortly after. Palace would go on to win the match with a goal from the returning [[Wilfried Zaha]]. Chelsea were without key players N'Golo Kanté and Álvaro Morata, with Kanté picking up a hamstring injury during the international break and Morata suffering the same injury against Manchester City. Chelsea lost back-to-back league fixtures for the first time in a year, when they lost to Liverpool and Arsenal. <ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41534304|title=Crystal Palace 2–1 Chelsea|publisher=BBC Sport|date=14 October 2017}}</ref>
On 18 October, Chelsea drew 3-3 at home against [[AS Roma]] in the UEFA Champions League. Chelsea, having lead 2-0 following goals from David Luiz and Eden Hazard, caved in to Roma's [[Edin Dzeko]] and [[Aleksandar Kolarov]] who between them scored 3 goals. With a late goal from Eden Hazard to equalise for the home side, Chelsea dropped their first points in the 2017-18 UEFA Champions League group stage. <ref>{url=http://www.goal.com/en-om/match/chelsea-v-roma/2ll82hyyj3lhoswptyb0a04tm}</ref>
[[File:Chelsea 2 Everton 1 (37914921192).jpg|thumb|left|upright|Pre-match handshakes before the [[EFL Cup]] clash with [[Everton F.C.|Everton]].]]
On 21 October, Chelsea enjoyed a 4-2 come-from-behind victory over [[Watford F.C.|Watford]]. Following a Pedro goal, Watford found themselves 2-1 up through goals from [[Abdoulaye Doucoure]] and [[Roberto Pereyra]]. However, Michy Batshuayi came off the bench to score a brace on either side of a Cesar Azpilicueta winner. The win snapped a 4 game winless streak in all competitions for Chelsea.<ref>{url=http://www.espn.co.uk/football/report?gameId=480824}</ref>
On 25 October, Chelsea progressed past the round of 16 in the EFL Cup by defeating Everton 2-1 in the first match for their interim manager, [[David Unsworth]]. Goals from Willian and Rudiger rendered a late [[Dominic Calvert-Lewin]] goal a mere consolation. <ref>{url=http://www.goal.com/en/match/chelsea-v-everton/d8x1smzdgzav7464n2g659y7e}</ref>
On 28 October, in the Premier League, Chelsea narrowly defeated [[A.F.C. Bournemouth|AFC Bournemouth]] 1-0 away from home. A goal from Eden Hazard sealed the points in a tight encounter. <ref>{url=https://www.standard.co.uk/sport/football/bournemouth-0-chelsea-1-eden-hazard-the-difference-as-blues-keep-pace-with-rivals-a3670551.html}</ref>
On 31 October, in their final October fixture, Chelsea fell to a poor 3-0 away defeat to [[A.S. Roma]] in the Champions League, and became the first English team to lose a Champions League fixture in 2017-18 as a result. The Blues fell behind after 39 seconds courtesy of a goal from [[Stephan El Shaarawy]], and they never looked like recovering after he scored his second goal of the game on 36 minutes. Chelsea had more shots throughout the match, but a third Roma goal scored by [[Diego Perotti]] in the second half sealed the contest. Results elsewhere kept Chelsea in the top two of their group, with Atletico Madrid drawing with Qarabag, however Chelsea's poor defensive performance left [[Antonio Conte]] with food for thought going into the month of November.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/41807331|title=AS Roma 3-0 Chelsea|publisher=BBC Sport|date=31 October 2017}}</ref>
===November===
On 5 November, Chelsea got the month off to a good start as they defeated long-time competitive rivals [[Manchester United F.C.|Manchester United]] 1-0 at Stamford Bridge, courtesy of a headed effort from [[Alvaro Morata]], scoring his first goal for the club since September. It was former Blues manager [[Jose Mourinho|Jose Mourinho's]] third straight loss at Stamford Bridge since he became United manager. The victory lifted Chelsea into fourth place, and moved them to within one point of Manchester United in second.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/41792809|title=Chelsea 1-0 Manchester United|publisher=BBC Sport|date=5 November 2017}}</ref>
On 18 November, in Chelsea's first match after the international break, they dispatched [[West Bromwich Albion F.C.|West Bromwich Albion]] 4-0 away from home in the Premier League, in a commanding performance that saw opposite number [[Tony Pulis]] sacked just days after the match. Alvaro Morata poked Chelsea in front on 17 minutes, the Spaniard scoring his eighth league goal of the season, while an [[Eden Hazard]] double either side of half time and a first half goal from Marcos Alonso sealed a comfortable win for Chelsea. The victory was Chelsea's fourth successive league win, while West Bromwich Albion remained without a win in all competitions since 22 August, a run of 11 games. Chelsea moved up to third, one point behind Manchester United.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/41951917|title=West Bromwich Albion 0-4 Chelsea|publisher=BBC Sport|date=18 November 2017}}</ref>
On 22 November, Chelsea sealed their progression to the knockout stage of the Champions League, by comfortably beating [[FK Qarabag]] 4-0 away from home, in a 5000 mile trip to Azerbaijan. Two goals from Willian, as well as spot-kicks from Eden Hazard and Cesc Fabregas, confirmed the Blues will finish in the top two of Group C with a game to spare.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/42060909|title=FK Qarabag 0-4 Chelsea|publisher=BBC Sport|date=22 November 2017}}</ref>
On 25 November, just three days after travelling to Azerbaijan, Chelsea earned a 1-1 league draw at [[Anfield]] against [[Liverpool F.C.|Liverpool]]. Former Chelsea player [[Mohamed Salah]] opened the scoring for Liverpool with a close range finish just after the hour mark, while Willian, continuing his good run of form, struck in the 85th minute through what appeared to be a cross looping over Simon Mignolet and into the far corner. The result was a repeat scoreline of last season's 1-1 draw at Anfield, ensuring that Chelsea remained unbeaten in their past seven visits to Anfield, a run stretching back to 2013. The draw, however, left Chelsea three points behind Manchester United in second, and eight points behind league leaders Manchester City.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/42035410|title=Liverpool 1-1 Chelsea|publisher=BBC Sport|date=25 November 2017}}</ref>
On 27 November, former Chelsea academy manager [[Dermot Drummy]] died aged 56. Drummy won the 2010 FA Youth Cup whilst working at the club - and later served as reserve-team manager before taking the role of international head coach in June 2014. Former Chelsea youth players that had been coached under him paid tribute to Drummy, including [[Nathan Ake]], [[Nathaniel Chalobah]], [[Patrick Bamford]] and [[Ruben Loftus-Cheek]].<ref>{{Cite news|url=http://www.dailymail.co.uk/sport/football/article-5123055/Ex-Chelsea-coach-Dermot-Drummy-dies-age-56.html|title=Ex-Chelsea coach and Crawley boss Dermot Drummy dies aged 56 as his former players including Nathaniel Chalobah and Ruben Loftus-Cheek pay tribute: 'You taught us to be men'|publisher=Daily Mail|date=27 November 2017}}</ref><ref>{{Cite news|url=http://www.chelseafc.com/news/latest-news/2017/11/dermot-drummy.html|title=Dermot Drummy|publisher=Chelsea Football Club Official Site|date=28 November 2017}}</ref>
On 29 November, Chelsea capped off the month of November with a hard fought 1-0 league victory against struggling [[Swansea City A.F.C.|Swansea City]]. Chelsea dominated the game but had to wait until the 55th minute for the breakthrough, with defender Antonio Rudiger heading in his first Premier League goal after N'Golo Kante's shot was deflected into his path. The game was marred by an incident involving manager Antonio Conte and match official [[Neil Swarbrick]], with the Italian spending the whole of the second half watching from a television feed in the dressing room after disputing Swarbrick's decision not to award a corner when the game was goalless. Conte later apologised for his conduct, stating "I was frustrated. For sure I made a mistake. During the game I suffer. With my players I suffer. It's a pity". Chelsea remained third in the table, three points behind Manchester United in second and eleven points behind runaway leaders [[Manchester City F.C.|Manchester City]].<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/42075943|title=Chelsea 1-0 Swansea City|publisher=BBC Sport|date=29 November 2017}}</ref>

On 2 December, Chelsea defeated newly-promoted [[Newcastle United F.C.|Newcastle United]] 3-1 at Stamford Bridge. [[Dwight Gayle]] put the visitors in front after 12 minutes, but Newcastle's lead was short lived as Eden Hazard and Álvaro Morata struck in the first half to send the Blues 2-1 up at the break. Hazard scored his second goal of the game in the second half, a chipped penalty after [[Matt Ritchie]] fouled Victor Moses in the area. The result kept Chelsea in touch with the two Manchester clubs after they had both won in the same gameweek, with the Blues remaining in third, but now three points ahead of Liverpool in fourth.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/42119935|title=Chelsea 3-1 Newcastle United|publisher=BBC Sport|date=2 December 2017}}</ref>
On 5 December, Chelsea drew 1-1 against Atletico Madrid on the final matchday of the Champions League. [[Saul Niguez|Saul Niguez's]] header opened the scoring in the 56th minute, before a [[Stefan Savic]] own-goal leveled the scoreline. The result saw Roma beat Chelsea to the top spot of Group C, on the head-to-head tiebreaker. The draw also caused Atletico Madrid to fail to progress to the knockout stages of the Champions League for the first time since they failed to qualify, in the [[2012-13 Atletico Madrid season|2012-13 season]].<ref>{{Cite news|url=http://www.mirror.co.uk/sport/football/match-reports/chelsea-1-1-atletico-madrid-11642940|title=Chelsea 1-1 Atletico Madrid: Stalemate sees Blues fail to top group and Spaniard crash out of Champions League|publisher=Mirror|date=6 December 2017}}</ref>
On 9 December, Chelsea's unbeaten league run since October came to an end after they lost 1–0 to [[West Ham United F.C.|West Ham United]] at the London Stadium. [[Marko Arnautovic]] scored for West Ham early in the first half, and Chelsea struggled to get a foothold in the game as they gifted [[David Moyes]] his first league win in charge of West Ham. Following the match, Antonio Conte admitted defeat in Chelsea's attempt to retain their Premier League crown, saying, "When you tell the truth, this is the truth. Now we have 11 points less than Manchester City [who had a game in hand]. In 16 games they won 15 and drew one. In 17 games we lost four. When you have a competitor like City and every game they are winning, it is very difficult to think you can fight for the title." <ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/42205607|title=West Ham United 1–0 Chelsea|publisher=BBC Sport|date=9 December 2017}}</ref><ref name=":0">{{Cite news|url=http://www.telegraph.co.uk/football/2017/12/12/huddersfield-vs-chelsea-premier-league-live-score-updates/|title=Huddersfield 1 Chelsea 3: Antonio Conte's side back to winning ways as they breeze to victory|last=Wallace|first=Sam|date=2017-12-12|work=The Telegraph|access-date=2017-12-21|last2=Bull|first2=J.

On 12 December, Chelsea returned to winning ways in the Premier League in a dominant 3-1 away win against newly-promoted [[Huddersfield Town A.F.C.|Huddersfield]]. Goals from Tiémoué Bakayoko, Willian, and Pedro rendered a late [[Laurent Depoitre]] strike mere consolation. <ref name=":0" />
On 16 December, Chelsea defeated [[Southampton F.C.|Southampton]] 1-0 at Stamford Bridge, courtesy of a Marcos Alonso free-kick, somewhat controversially occurring thirty seconds past the two allotted minutes of added time in the first half. In an otherwise extremely tight affair, [[Charlie Austin]] had the best chance for the away side with his first touch of the ball after he came on as a substitute. However, one goal proved to be enough for ''the Blues'' to hold on to all three points. <ref>{{Cite web|url=http://www.espn.co.uk/football/report?gameId=480732|title=Chelsea vs. Southampton - Football Match Report - December 16, 2017 - ESPN|website=ESPN.com|access-date=2017-12-21}}</ref>
On 20 December, Chelsea defeated Bournemouth in the [[EFL Cup]] quarter-finals 2-1. Conte rotated the team heavily, making eight changes from the side that beat Huddersfield. [[Ethan Ampadu]] was named man of the match after an admirable performance at centre-back, despite an early tackle that injured Bournemouth striker [[Jermain Defoe]]. Chelsea took the lead through Willian, with Cesc Fàbregas and [[Kenedy (footballer)|Kenedy]] heavily involved in the build-up. Chelsea dominated the majority of the first half, but Bournemouth were reinvigorated following the half-time break. Their efforts finally payed off in the 90th minute, when [[Dan Gosling]] curled in from outside of the eighteen yard box.The match looked certain to go into extra time, but following the kick off, substitute Álvaro Morata almost immediately scored the winner. Following the match, Chelsea were drawn against Arsenal in the semi-finals. In the other match, high-flying Manchester City were drawn against [[Bristol City F.C.|Bristol City]], who shockingly defeated their next opponent's city rivals, Manchester United. <ref>{{Cite web|url=http://www.espnfc.com.au/football/report?gameId=498025|title=Chelsea vs. AFC Bournemouth - Football Match Report - December 20, 2017 - ESPN|website=ESPNFC.com|access-date=2017-12-21}}</ref><ref>{{Cite news|url=http://www.skysports.com/football/news/11938/11180100/efl-selects-arsenal-v-chelsea-carabao-cup-semi-final-for-video-assistant-referee-trial|title=EFL selects Arsenal v Chelsea Carabao Cup semi-final for video assistant referee trial|work=Sky Sports|access-date=2017-12-21|language=en}}</ref>
On 23 December, Chelsea visited Goodison Park and drew 0-0 against Everton. With striker Álvaro Morata suspended due to yellow card accumulation, Chelsea played Eden Hazard as a [[false nine]]. However, Chelsea lacked many scoring opportunities and ultimately were made to pay as Everton won a point in their final home game of the season. <ref>{{Cite web|url=http://www.goal.com/en-us/match/everton-v-chelsea/9n0ipmwa20bhrdafhcfcof8tm|title=Everton v Chelsea Match Report, 12/23/17, Premier League {{!}} Goal.com|website=www.goal.com|language=en|access-date=2018-01-04}}</ref>
On 26 December, Chelsea took on [[Brighton & Hove Albion F.C.|Brighton]] at Stamford Bridge. Following a quiet first half, in which the only clear-cut chance came form Tiémoué Bakayoko, Chelsea scored 53 seconds after the break, courtesy of an Álvaro Morata goal, assisted by César Azpilicueta. It was the sixth time that the Spaniards linked up during the season to score. Later on, Marcos Alonso headed in from a corner as ''the Blues'' comfortably won 2-0 to extend their unbeaten run on [[Boxing Day]] to 14 games.<ref>{{Cite news|url=http://www.skysports.com/football/chelsea-vs-brighton/373288|title=Chelsea 2-0 Brighton: Alvaro Morata and Marcos Alonso strike in victory|work=Sky Sports|access-date=2018-01-06|language=en}}</ref>
On 30 December, Chelsea played their final match of 2017 against Stoke City, winning with ease 5-0. Due to fixture congestion in the festive period, Chelsea rotated their lineup slightly, resting Eden Hazard and Cesc Fàbregas. Stoke City, however, started a completely rotated lineup, with manager, and former Chelsea player, [[Mark Hughes]] prioritizing the upcoming Newcastle game. After two goals in the opening 10 minutes from Antonio Rüdiger and Danny Drinkwater, Chelsea looked set to dominate the match, and did so, scoring three more goals through Pedro, Willian, and Davide Zappacosta. Chelsea ended the calendar year in second place, 1 point ahead of Manchester United and 14 points behind runaway leaders, Manchester City.
=== January ===
On 1 January 2018, Diego Costa officially departed the club and signed for Atletico Madrid. <ref>{{Cite web|url=http://en.atleticodemadrid.com/noticias/diego-costa-is-now-an-atletico|title=Club Atlético de Madrid - Diego Costa is now an Atlético|website=Club Atlético de Madrid|language=en|access-date=2018-01-06}}</ref>
On 3 January, Chelsea took on Arsenal in a thrilling encounter which ended 2-2 away at the Emirates Stadium. Jack Wilshere opened the scoring after the break, following an end-to-end first half, headlined by a clear-cut chance missed by Álvaro Morata in the fifteenth minute. However, following the opener, Chelsea scored twice, once courtesy of an Eden Hazard penalty, and again in the 84th minute, when Marcos Alonso scored what looked to be the winner. However, in the 92nd minute, Héctor Bellerín scored a late equaliser into the bottom left corner of the goal, earning both teams a point. In the last minute of stoppage time, Morata missed another clear-cut chance, and, substitute Davide Zappacosta lashed the rebound goalwards, only to see it bounce back off of the crossbar with virtually the last kick of the game. Following the match, Morata was criticised heavily due to his poor performance. <ref>{{Cite web|url=http://www.goal.com/en-in/match/arsenal-v-chelsea/report/9r6lwr6z8p2lr8e4tguwby3qi|title=Arsenal v Chelsea Match Report, 03/01/2018, Premier League {{!}} Goal.com|website=www.goal.com|language=en|access-date=2018-01-06}}</ref>
On 5 January 2018, Chelsea signed 24-year-old Englishman Ross Barkley from Everton for a reported £15 million. He was assigned the number 8 shirt, previously occupied by [[Oscar (footballer, born 1991)|Oscar]] and [[Frank Lampard]]. Barkley did not make any appearances for Everton in the 2017-18 season, so he was eligible to play in all of Chelsea's competitions. Following signing, Barkley said, "To be given a fresh start at a new club like Chelsea, it's unbelievable for me. I'm looking forward to continuing where I left off at the end of last season and hoping to improve and add more goals to my game." <ref name=":1" />

On 21 September, the long-protracted transfer saga surrounding exiled striker [[Diego Costa]] came to an end as Chelsea agreed a fee with [[Atlético Madrid]] for his transfer, to be completed in January after the expiry of the Spanish club's transfer ban.<ref>{{Cite news|url=https://www.chelseafc.com/news/latest-news/2017/09/diego-costa-transfer-agreed.html|title=Diego Costa transfer agreed|publisher=Chelsea Football Club Official Site|date=21 September 2017}}</ref> He leaves Chelsea having scored 58 goals in 120 appearances for ''the Blues'', including 20 in the Premier League last season as Chelsea won the title.<ref>{{Cite news|url=https://www.bbc.co.uk/sport/amp/football/41369356|title=Diego Costa: Striker says he will always have 'special affection' for Chelsea|publisher=BBC Sport|date=21 September 2017}}</ref>
On 23 September, Chelsea earned a fourth Premier League victory in five matches after thrashing Stoke City 4–0 away. Álvaro Morata opened the scoring for ''the Blues'', with Pedro adding a second before half-time. Morata completed a hat-trick in the second half, Chelsea's first Premier League hat-trick since 2014, to keep ''the Blues'' in third position and within three points of the two Manchester clubs at the top of the table.<ref>{{Cite news|url=http://www.bbc.com/sport/football/41290319|title=Stoke City 0–4 Chelsea|publisher=BBC Sport|date=23 September 2017}}</ref>
On 27 September, Chelsea beat Atlético Madrid 2–1 away in a Champions League group stage match, making history in the process by becoming the first ever English club to defeat Atlético away from home in a European competition. Chelsea fell behind late in the first half after David Luiz conceded a penalty, which [[Antoine Griezmann]] converted. Morata leveled proceedings early in the second half with a header. The match looked to be finishing as a draw until Michy Batshuayi snatched a winner for Chelsea at the death. The result sees ''the Blues'' go top of Group C, four points ahead of Atlético and Roma after two match.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41379696|title=Atletico Madrid 1–2 Chelsea|publisher=BBC Sport|date=27 September 2017}}</ref>
On 30 September, three days after their Champions League heroics, Chelsea lost 1–0 at Stamford Bridge to league leaders Manchester City in a very poor performance that culminated in Chelsea only having two shots on target in the whole match. The defeat sees the gap between the two sides widen to six points, with Chelsea slipping into fourth.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41370356|title=Chelsea 0–1 Manchester City|publisher=BBC Sport|date=30 September 2017}}</ref>
===October===

On 14 October, in their first league match after the international break, Chelsea fell to a very poor 2–1 away defeat against bottom Premier League side Crystal Palace. The home side scored their first goals and earned their first points of the season after losing their opening seven fixtures without scoring. An own goal from César Azpilicueta opened the scoring early in the first half before Tiémoué Bakayoko leveled proceedings shortly after. Palace would go on to win the match with a goal from the returning [[Wilfried Zaha]]. Chelsea were without key players N'Golo Kanté and Álvaro Morata, with Kanté picking up a hamstring injury during the international break and Morata suffering the same injury against Manchester City. Chelsea lost back-to-back league fixtures for the first time in a year, when they lost to Liverpool and Arsenal. <ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41534304|title=Crystal Palace 2–1 Chelsea|publisher=BBC Sport|date=14 October 2017}}</ref>
On 18 October, Chelsea drew 3-3 at home against [[AS Roma]] in the UEFA Champions League. Chelsea, having lead 2-0 following goals from David Luiz and Eden Hazard, caved in to Roma's [[Edin Dzeko]] and [[Aleksandar Kolarov]] who between them scored 3 goals. With a late goal from Eden Hazard to equalise for the home side, Chelsea dropped their first points in the 2017-18 UEFA Champions League group stage. <ref>{url=http://www.goal.com/en-om/match/chelsea-v-roma/2ll82hyyj3lhoswptyb0a04tm}</ref>
[[File:Chelsea 2 Everton 1 (37914921192).jpg|thumb|left|upright|Pre-match handshakes before the [[EFL Cup]] clash with [[Everton F.C.|Everton]].]]
On 21 October, Chelsea enjoyed a 4-2 come-from-behind victory over [[Watford F.C.|Watford]]. Following a Pedro goal, Watford found themselves 2-1 up through goals from [[Abdoulaye Doucoure]] and [[Roberto Pereyra]]. However, Michy Batshuayi came off the bench to score a brace on either side of a Cesar Azpilicueta winner. The win snapped a 4 game winless streak in all competitions for Chelsea.<ref>{url=http://www.espn.co.uk/football/report?gameId=480824}</ref>
On 25 October, Chelsea progressed past the round of 16 in the EFL Cup by defeating Everton 2-1 in the first match for their interim manager, [[David Unsworth]]. Goals from Willian and Rudiger rendered a late [[Dominic Calvert-Lewin]] goal a mere consolation. <ref>{url=http://www.goal.com/en/match/chelsea-v-everton/d8x1smzdgzav7464n2g659y7e}</ref>
On 28 October, in the Premier League, Chelsea narrowly defeated [[A.F.C. Bournemouth|AFC Bournemouth]] 1-0 away from home. A goal from Eden Hazard sealed the points in a tight encounter. <ref>{url=https://www.standard.co.uk/sport/football/bournemouth-0-chelsea-1-eden-hazard-the-difference-as-blues-keep-pace-with-rivals-a3670551.html}</ref>
On 31 October, in their final October fixture, Chelsea fell to a poor 3-0 away defeat to [[A.S. Roma]] in the Champions League, and became the first English team to lose a Champions League fixture in 2017-18 as a result. The Blues fell behind after 39 seconds courtesy of a goal from [[Stephan El Shaarawy]], and they never looked like recovering after he scored his second goal of the game on 36 minutes. Chelsea had more shots throughout the match, but a third Roma goal scored by [[Diego Perotti]] in the second half sealed the contest. Results elsewhere kept Chelsea in the top two of their group, with Atletico Madrid drawing with Qarabag, however Chelsea's poor defensive performance left [[Antonio Conte]] with food for thought going into the month of November.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/41807331|title=AS Roma 3-0 Chelsea|publisher=BBC Sport|date=31 October 2017}}</ref>
===November===
On 5 November, Chelsea got the month off to a good start as they defeated long-time competitive rivals [[Manchester United F.C.|Manchester United]] 1-0 at Stamford Bridge, courtesy of a headed effort from [[Alvaro Morata]], scoring his first goal for the club since September. It was former Blues manager [[Jose Mourinho|Jose Mourinho's]] third straight loss at Stamford Bridge since he became United manager. The victory lifted Chelsea into fourth place, and moved them to within one point of Manchester United in second.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/41792809|title=Chelsea 1-0 Manchester United|publisher=BBC Sport|date=5 November 2017}}</ref>
On 18 November, in Chelsea's first match after the international break, they dispatched [[West Bromwich Albion F.C.|West Bromwich Albion]] 4-0 away from home in the Premier League, in a commanding performance that saw opposite number [[Tony Pulis]] sacked just days after the match. Alvaro Morata poked Chelsea in front on 17 minutes, the Spaniard scoring his eighth league goal of the season, while an [[Eden Hazard]] double either side of half time and a first half goal from Marcos Alonso sealed a comfortable win for Chelsea. The victory was Chelsea's fourth successive league win, while West Bromwich Albion remained without a win in all competitions since 22 August, a run of 11 games. Chelsea moved up to third, one point behind Manchester United.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/41951917|title=West Bromwich Albion 0-4 Chelsea|publisher=BBC Sport|date=18 November 2017}}</ref>
On 22 November, Chelsea sealed their progression to the knockout stage of the Champions League, by comfortably beating [[FK Qarabag]] 4-0 away from home, in a 5000 mile trip to Azerbaijan. Two goals from Willian, as well as spot-kicks from Eden Hazard and Cesc Fabregas, confirmed the Blues will finish in the top two of Group C with a game to spare.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/42060909|title=FK Qarabag 0-4 Chelsea|publisher=BBC Sport|date=22 November 2017}}</ref>
On 25 November, just three days after travelling to Azerbaijan, Chelsea earned a 1-1 league draw at [[Anfield]] against [[Liverpool F.C.|Liverpool]]. Former Chelsea player [[Mohamed Salah]] opened the scoring for Liverpool with a close range finish just after the hour mark, while Willian, continuing his good run of form, struck in the 85th minute through what appeared to be a cross looping over Simon Mignolet and into the far corner. The result was a repeat scoreline of last season's 1-1 draw at Anfield, ensuring that Chelsea remained unbeaten in their past seven visits to Anfield, a run stretching back to 2013. The draw, however, left Chelsea three points behind Manchester United in second, and eight points behind league leaders Manchester City.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/42035410|title=Liverpool 1-1 Chelsea|publisher=BBC Sport|date=25 November 2017}}</ref>
On 27 November, former Chelsea academy manager [[Dermot Drummy]] died aged 56. Drummy won the 2010 FA Youth Cup whilst working at the club - and later served as reserve-team manager before taking the role of international head coach in June 2014. Former Chelsea youth players that had been coached under him paid tribute to Drummy, including [[Nathan Ake]], [[Nathaniel Chalobah]], [[Patrick Bamford]] and [[Ruben Loftus-Cheek]].<ref>{{Cite news|url=http://www.dailymail.co.uk/sport/football/article-5123055/Ex-Chelsea-coach-Dermot-Drummy-dies-age-56.html|title=Ex-Chelsea coach and Crawley boss Dermot Drummy dies aged 56 as his former players including Nathaniel Chalobah and Ruben Loftus-Cheek pay tribute: 'You taught us to be men'|publisher=Daily Mail|date=27 November 2017}}</ref><ref>{{Cite news|url=http://www.chelseafc.com/news/latest-news/2017/11/dermot-drummy.html|title=Dermot Drummy|publisher=Chelsea Football Club Official Site|date=28 November 2017}}</ref>
On 29 November, Chelsea capped off the month of November with a hard fought 1-0 league victory against struggling [[Swansea City A.F.C.|Swansea City]]. Chelsea dominated the game but had to wait until the 55th minute for the breakthrough, with defender Antonio Rudiger heading in his first Premier League goal after N'Golo Kante's shot was deflected into his path. The game was marred by an incident involving manager Antonio Conte and match official [[Neil Swarbrick]], with the Italian spending the whole of the second half watching from a television feed in the dressing room after disputing Swarbrick's decision not to award a corner when the game was goalless. Conte later apologised for his conduct, stating "I was frustrated. For sure I made a mistake. During the game I suffer. With my players I suffer. It's a pity". Chelsea remained third in the table, three points behind Manchester United in second and eleven points behind runaway leaders [[Manchester City F.C.|Manchester City]].<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/42075943|title=Chelsea 1-0 Swansea City|publisher=BBC Sport|date=29 November 2017}}</ref>

[[File:West Ham 1 Chelsea 0 (38904760282).jpg|thumb|right|Inside the [[London Stadium]] during the [[London derbies|London derby]] defeat with [[West Ham United F.C.|West Ham United]].]]
On 2 December, Chelsea defeated newly-promoted [[Newcastle United F.C.|Newcastle United]] 3-1 at Stamford Bridge. [[Dwight Gayle]] put the visitors in front after 12 minutes, but Newcastle's lead was short lived as Eden Hazard and Álvaro Morata struck in the first half to send the Blues 2-1 up at the break. Hazard scored his second goal of the game in the second half, a chipped penalty after [[Matt Ritchie]] fouled Victor Moses in the area. The result kept Chelsea in touch with the two Manchester clubs after they had both won in the same gameweek, with the Blues remaining in third, but now three points ahead of Liverpool in fourth.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/42119935|title=Chelsea 3-1 Newcastle United|publisher=BBC Sport|date=2 December 2017}}</ref>
On 5 December, Chelsea drew 1-1 against Atletico Madrid on the final matchday of the Champions League. [[Saul Niguez|Saul Niguez's]] header opened the scoring in the 56th minute, before a [[Stefan Savic]] own-goal leveled the scoreline. The result saw Roma beat Chelsea to the top spot of Group C, on the head-to-head tiebreaker. The draw also caused Atletico Madrid to fail to progress to the knockout stages of the Champions League for the first time since they failed to qualify, in the [[2012-13 Atletico Madrid season|2012-13 season]].<ref>{{Cite news|url=http://www.mirror.co.uk/sport/football/match-reports/chelsea-1-1-atletico-madrid-11642940|title=Chelsea 1-1 Atletico Madrid: Stalemate sees Blues fail to top group and Spaniard crash out of Champions League|publisher=Mirror|date=6 December 2017}}</ref>
On 9 December, Chelsea's unbeaten league run since October came to an end after they lost 1–0 to [[West Ham United F.C.|West Ham United]] at the London Stadium. [[Marko Arnautovic]] scored for West Ham early in the first half, and Chelsea struggled to get a foothold in the game as they gifted [[David Moyes]] his first league win in charge of West Ham. Following the match, Antonio Conte admitted defeat in Chelsea's attempt to retain their Premier League crown, saying, "When you tell the truth, this is the truth. Now we have 11 points less than Manchester City [who had a game in hand]. In 16 games they won 15 and drew one. In 17 games we lost four. When you have a competitor like City and every game they are winning, it is very difficult to think you can fight for the title." <ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/42205607|title=West Ham United 1–0 Chelsea|publisher=BBC Sport|date=9 December 2017}}</ref><ref name=":0">{{Cite news|url=http://www.telegraph.co.uk/football/2017/12/12/huddersfield-vs-chelsea-premier-league-live-score-updates/|title=Huddersfield 1 Chelsea 3: Antonio Conte's side back to winning ways as they breeze to victory|last=Wallace|first=Sam|date=2017-12-12|work=The Telegraph|access-date=2017-12-21|last2=Bull|first2=J.

On 12 December, Chelsea returned to winning ways in the Premier League in a dominant 3-1 away win against newly-promoted [[Huddersfield Town A.F.C.|Huddersfield]]. Goals from Tiémoué Bakayoko, Willian, and Pedro rendered a late [[Laurent Depoitre]] strike mere consolation. <ref name=":0" />
On 16 December, Chelsea defeated [[Southampton F.C.|Southampton]] 1-0 at Stamford Bridge, courtesy of a Marcos Alonso free-kick, somewhat controversially occurring thirty seconds past the two allotted minutes of added time in the first half. In an otherwise extremely tight affair, [[Charlie Austin]] had the best chance for the away side with his first touch of the ball after he came on as a substitute. However, one goal proved to be enough for ''the Blues'' to hold on to all three points. <ref>{{Cite web|url=http://www.espn.co.uk/football/report?gameId=480732|title=Chelsea vs. Southampton - Football Match Report - December 16, 2017 - ESPN|website=ESPN.com|access-date=2017-12-21}}</ref>
On 20 December, Chelsea defeated Bournemouth in the [[EFL Cup]] quarter-finals 2-1. Conte rotated the team heavily, making eight changes from the side that beat Huddersfield. [[Ethan Ampadu]] was named man of the match after an admirable performance at centre-back, despite an early tackle that injured Bournemouth striker [[Jermain Defoe]]. Chelsea took the lead through Willian, with Cesc Fàbregas and [[Kenedy (footballer)|Kenedy]] heavily involved in the build-up. Chelsea dominated the majority of the first half, but Bournemouth were reinvigorated following the half-time break. Their efforts finally payed off in the 90th minute, when [[Dan Gosling]] curled in from outside of the eighteen yard box.The match looked certain to go into extra time, but following the kick off, substitute Álvaro Morata almost immediately scored the winner. Following the match, Chelsea were drawn against Arsenal in the semi-finals. In the other match, high-flying Manchester City were drawn against [[Bristol City F.C.|Bristol City]], who shockingly defeated their next opponent's city rivals, Manchester United. <ref>{{Cite web|url=http://www.espnfc.com.au/football/report?gameId=498025|title=Chelsea vs. AFC Bournemouth - Football Match Report - December 20, 2017 - ESPN|website=ESPNFC.com|access-date=2017-12-21}}</ref><ref>{{Cite news|url=http://www.skysports.com/football/news/11938/11180100/efl-selects-arsenal-v-chelsea-carabao-cup-semi-final-for-video-assistant-referee-trial|title=EFL selects Arsenal v Chelsea Carabao Cup semi-final for video assistant referee trial|work=Sky Sports|access-date=2017-12-21|language=en}}</ref>
On 23 December, Chelsea visited Goodison Park and drew 0-0 against Everton. With striker Álvaro Morata suspended due to yellow card accumulation, Chelsea played Eden Hazard as a [[false nine]]. However, Chelsea lacked many scoring opportunities and ultimately were made to pay as Everton won a point in their final home game of the season. <ref>{{Cite web|url=http://www.goal.com/en-us/match/everton-v-chelsea/9n0ipmwa20bhrdafhcfcof8tm|title=Everton v Chelsea Match Report, 12/23/17, Premier League {{!}} Goal.com|website=www.goal.com|language=en|access-date=2018-01-04}}</ref>
On 26 December, Chelsea took on [[Brighton & Hove Albion F.C.|Brighton]] at Stamford Bridge. Following a quiet first half, in which the only clear-cut chance came form Tiémoué Bakayoko, Chelsea scored 53 seconds after the break, courtesy of an Álvaro Morata goal, assisted by César Azpilicueta. It was the sixth time that the Spaniards linked up during the season to score. Later on, Marcos Alonso headed in from a corner as ''the Blues'' comfortably won 2-0 to extend their unbeaten run on [[Boxing Day]] to 14 games.<ref>{{Cite news|url=http://www.skysports.com/football/chelsea-vs-brighton/373288|title=Chelsea 2-0 Brighton: Alvaro Morata and Marcos Alonso strike in victory|work=Sky Sports|access-date=2018-01-06|language=en}}</ref>
On 30 December, Chelsea played their final match of 2017 against Stoke City, winning with ease 5-0. Due to fixture congestion in the festive period, Chelsea rotated their lineup slightly, resting Eden Hazard and Cesc Fàbregas. Stoke City, however, started a completely rotated lineup, with manager, and former Chelsea player, [[Mark Hughes]] prioritizing the upcoming Newcastle game. After two goals in the opening 10 minutes from Antonio Rüdiger and Danny Drinkwater, Chelsea looked set to dominate the match, and did so, scoring three more goals through Pedro, Willian, and Davide Zappacosta. Chelsea ended the calendar year in second place, 1 point ahead of Manchester United and 14 points behind runaway leaders, Manchester City.
=== January ===
On 1 January 2018, Diego Costa officially departed the club and signed for Atletico Madrid. <ref>{{Cite web|url=http://en.atleticodemadrid.com/noticias/diego-costa-is-now-an-atletico|title=Club Atlético de Madrid - Diego Costa is now an Atlético|website=Club Atlético de Madrid|language=en|access-date=2018-01-06}}</ref>
On 3 January, Chelsea took on Arsenal in a thrilling encounter which ended 2-2 away at the Emirates Stadium. Jack Wilshere opened the scoring after the break, following an end-to-end first half, headlined by a clear-cut chance missed by Álvaro Morata in the fifteenth minute. However, following the opener, Chelsea scored twice, once courtesy of an Eden Hazard penalty, and again in the 84th minute, when Marcos Alonso scored what looked to be the winner. However, in the 92nd minute, Héctor Bellerín scored a late equaliser into the bottom left corner of the goal, earning both teams a point. In the last minute of stoppage time, Morata missed another clear-cut chance, and, substitute Davide Zappacosta lashed the rebound goalwards, only to see it bounce back off of the crossbar with virtually the last kick of the game. Following the match, Morata was criticised heavily due to his poor performance. <ref>{{Cite web|url=http://www.goal.com/en-in/match/arsenal-v-chelsea/report/9r6lwr6z8p2lr8e4tguwby3qi|title=Arsenal v Chelsea Match Report, 03/01/2018, Premier League {{!}} Goal.com|website=www.goal.com|language=en|access-date=2018-01-06}}</ref>
On 5 January 2018, Chelsea signed 24-year-old Englishman Ross Barkley from Everton for a reported £15 million. He was assigned the number 8 shirt, previously occupied by [[Oscar (footballer, born 1991)|Oscar]] and [[Frank Lampard]]. Barkley did not make any appearances for Everton in the 2017-18 season, so he was eligible to play in all of Chelsea's competitions. Following signing, Barkley said, "To be given a fresh start at a new club like Chelsea, it's unbelievable for me. I'm looking forward to continuing where I left off at the end of last season and hoping to improve and add more goals to my game." <ref name=":1" />
