The Blues fell behind to an excellent Kevin De Bruyne strike on 67 minutes, and they failed to muster a response as they fell to a disappointing defeat.
Antonio Conte’s men are now six points adrift from City and Manchester United, and also behind Tottenham following today’s results.
It was a bad day for the hosts at Stamford Bridge, with star striker Alvaro Morata substituted with an injury during the first half.
After the international break, Chelsea head to Crystal Palace for what should be a much more straightforward fixture against the league’s bottom club.
Courtois: 7, made some key saves. Couldn’t do much against KDB’s shot.
Rudiger: 7, Played well except being found out a couple of times.
Christensen: 7, His performance bodes well for the future. Pep Guardiola had a conversation with him.
Cahill: 6, The captain saw Chelsea lose the first game this season that he has finished.
Azpilicueta: 7, Couldn’t make a telling contribution from his starting position.
Kante: 7, Was full of energy but no end product.
Bakayoko: 6, was subpar.
Fabregas: 6, Tried a couple of good balls over the defence but otherwise lacklustre.
Alonso: 7, Tried.
Hazard: 6, Couldn’t carry the weight of the team till the end as he played 90 minutes against Atletico.
Morata: N/A, Injured
Willian: 6, Deplorable.
Moses To Report For Intl Duty In Good Health, Benched
Manchester City put up one of the best performances in the Premier League so far this season, beating Chelsea 1-0 at Stamford Bridge on Saturday evening.
The good news for manager Gernot Rohr and the Super Eagles faithful is that Victor Moses was not utilized by Antonio Conte, meaning the Nigeria international will be in good health when he reports for international duty early next week.
Before today’s contest, Moses had started all the five matches in which he was named in the Blues 18-man squad.
Manchester City dominated possession in the first half but could not penetrate Chelsea’s defense, with Fernandinho, Gabriel Jesus and David Silva having the best of their chances.
Kevin de Bruyne scored an absolute belter to give Pep Guardiola’s side the lead midway through the second half.
On 84 minutes, Gabriel Jesus had a great chance to double the visitors’ advantage, but his effort was cleared off the line by Rudiger.
City youngster Tosin Adarabioyo was not named in the 18-man squad at the home of the champions.
