Goals; Chelsea- Kante (44') David Luiz (78')
Goals from Kante and David Luiz inflicted Manchester City's first defeat of the season as the Champions were knocked off the top by Liverpool with the help of Chelsea as the Royal Blues beat the Light Blues 2-0 at Stamford Bridge.
Maurizio Sarri's side bounced back from the disappointment of losing at Wolves in midweek to end City's 21-game unbeaten league run stretching back to April, and a sequence of 14 unbeaten games away from home.
City paid for a lack of ruthlessness as they dominated the first half completely, only to be struck by a Chelsea smash-and-grab right on half-time as N'Golo Kante fired high past Ederson from Eden Hazard's pass.
Chelsea gained confidence and momentum and improved after the break, securing the win with 12 minutes left when David Luiz's glancing header following a corner bounced in off the far post.
They closed out the win to give Sarri his first triumph over Pep Guardiola and leave Liverpool top by one point following their convincing 4-0 win at Bournemouth earlier.
City was made to pay for lacking their killer touch. But this wasn't helped by the fact that their 2 best players- De Bruyne and Agüero prior to this game were out with injuries, meaning that Guardiola couldn't put out his full team. It also didn't help that David Silva got injured in the second half. These next few weeks will really test out Manchester City squad depth and character. Can they bounce back and regain top spot over Liverpool in the next few weeks?
On the Other hand for Sarri, he deserves a lot of credit for his tactics today- especially playing a false nine formation which worked really well in the second half, as all of the front three linked up really well and produced some lovely flowing football to cause City multiple problems.
Kepa kept his 8th clean sheet of the season. He is now level on clean sheets with Ederson, but still 2 behind Liverpool's Alisson. This has shown his positive start to life at Chelsea so far under Sarri.
David Luiz (MOTM) and Kante were the standout performances from this performance, but questions will still be asked of Alonso due too the fact that he was exploited by the likes of Sterling and Mahrez.
Chelsea Manager- Maurizio Sarri
"I am very happy with the win because it is not very easy to win against Manchester City or Pep Guardiola. I am happy with the mentality of the team in this match.
"It is difficult for us to find motivation but when we have it, we are a very strong team. Today we played with a very good level of application, determination and the right level of aggression.
"My players have to continue like this. We started well in the second half and in the end, we deserved to win." - Maurizio Sarri
Manchester City Manager- Pep Guardiola
"At this level and in the Champions League, the quality of the opponents means they only need a half a chance to score. That was the reality."
Despite slipping a point behind the Reds, the Spaniard rejected the notion his team had an "off day".
"If you think that, you didn't see the game," he told BBC Sport. "In the first half, we were exceptional.
"In general, we were fantastic. I don't have any regrets. We came and showed we wanted to win. We created chances. They had one in 44 minutes and we conceded a goal. Sometimes that happens.
"It is emotional for me to see these players do what they do every three days. We were outstanding except for five to eight minutes." - Pep Guardiola

Position in the Premier League table
Chelsea moves above Arsenal into third place with 34 points, but have a better goal difference than the Gunners. However, they are likely to move down to fourth if Tottenham beat Leicester tonight in the evening kick off. Manchester City move down to second with 41 points, but are 1 point off Klopp's unbeaten reds so far this season! However City does have the better goal difference, so it is still all to play for...
Next games for both teams
Both teams play in Europe in midweek, completing groups from which they have already qualified. City host Hoffenheim in the Champions League on Wednesday and Chelsea have a Europa League trip to Vidi on Thursday.
