Manchester City walked away with all three points from the Premier League champions' home. Kevin De Bruyne scored the one goal of the game as Chelsea struggle to find feet.
Here are the talking points from the game:
#5 - Antonio Conte's costly mistakes
From the starting XI to substitutions, Antonio Conte made mistake after mistake in the loss to Manchester City. Victor Moses was benched but instead of playing Zappacosta, he opted for Gary Cahill with Azpilicueta playing wing-back.
The move failed drastically and Manchester City capitalized on it. Antonio Rudiger was having a tough time with Leroy Sane and Azpilicueta was confused a lot of time on whether he should be attacking or staying back.
When Morata got injured, instead of bringing on Batshuayi, Conte opted for Willian. He expected the Brazilian and Hazard to get behind the Manchester City defenders but the duo was not able to link up at all.
