Chelsea vs Manchester City first half
City settled quickly and dominated the early possession, but opportunities were hard to create against a well-organised Chelsea defence.
The home side carved out the first decent opening of the game in the 15th minute when Christian Pulisic tried to break beyond the City back line but was denied by an excellent tackle from John Stones.
Pulisic was injured in the challenge and he became the second Chelsea forward forced off through injury after Raheem Sterling was replaced inside five minutes.
Erling Haaland finally got into the game towards the end of the first half as he raced onto a Gundogan through-ball, an exquisite first touch gave him a sight of goal but he fired a powerful strike just over the bar.
Chelsea vs Manchester City second half
Pep Guardiola made a double change during the break, Rico Lewis and Manuel Akanji replaced Cancelo and Walker.
City were quick out of the blocks and almost found an opener in the 50th minute when a deep cross from De Bruyne picked out Ake, but his header came back off the post.
Riyad Mahrez goal
Guardiola then made another two changes with Mahrez and Grealish and barely two minutes later they combined for the opening goal.
A move started by Ederson ended with Grealish running onto a De Bruyne pass and threading a perfect pass for Mahrez to finish at the far post.
Chelsea pushed men forward and took more risks to try to grab an equaliser but Man City held on for a crucial win.
