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.

The Blues fought back from 3–0 down with goals from debutant [[Álvaro Morata]] and [[David Luiz]],

After the defeat to the Clarets, Chelsea bounced back with a 2-1 away victory over [[Tottenham Hotspur]] at the [[Wembley Stadium]]. [[Marcos Alonso Mendoza]] scored a double, a free kick and a strike late in the game, while Spurs scored by a own goal from [[Michy Batshuayi]]. That was Spurs' first game at home this season and their first PL home game at the Wembley.

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. Chelsea's performance was marred by referee [[Craig Pawson]], two of their players receiving red cards, the first being captain [[Gary Cahill]] in the early stages of the game, and the second being [[Cesc Fàbregas]] towards the closing stages of the game. The Blues fought back from 3–0 down with goals from debutant [[Álvaro Morata]] and [[David Luiz]],
but ultimately lost the game.<ref>{{cite news|url=http://m.bbc.co.uk/sport/football/40835426|title=Chelsea 2–3 Burnley|publisher=BBC Sport|date=12 August 2017}}</ref> The defeat drew parallels to [[Leicester City F.C.|Leicester City]]'s 2015–16 title defence, where Leicester also lost their opening match against [[Hull City A.F.C.|Hull City]] at home, who were eventually relegated. After the defeat to the Clarets, Chelsea bounced back with a 2-1 away victory over [[Tottenham Hotspur]] at the [[Wembley Stadium]]. [[Marcos Alonso Mendoza]] scored a double, a free kick and a strike late in the game, while Spurs scored by a own goal from [[Michy Batshuayi]]. That was Spurs' first game at home this season and their first PL home game at the Wembley.
