After an eventful week, where Chelsea opened their title defence with a draw against Swansea followed by a spat between the first team's medics and Mourinho, Chelsea had more than enough desire to roll over Manchester City and get their season back on track.
Jose Mourinho named a strong starting XI despite losing out on Thibaut Courtois and Oscar due to suspension and injury, respectively and City included Sergio Aguero in the starting lineup after he came on as a sub against West Brom in City's season opener.
Despite naming an equally strong, if not better, lineup, Mourinho's Chelsea were outclassed, outwitted and exploited by a resilient Manchester City side over 90 minutes.

Cesc Fabregas, who racked up 18 assists in his first season in the Premier League after returning from Barcelona, was outsmarted by his fellow Spaniard David Silva. City's midfield neutralised Nemanja Matic's physical dominance over the course of the game.
John Terry, who was indomitable throughout Chelsea's rampage last season, cut a frustrating figure throughout first half and gifted City the opener by being out of position and lastly, Eden Hazard was anonymous until the 52nd minute, when he managed to register his and Chelsea's first shot of the game.
The game was all about City from the first whistle to the final whistle. Yaya Toure and Fernandinho were the focal points of City's attacks and they managed to shut out Chelsea's midfield and hence preventing any counter attacks.
Sergio Aguero took apart the entire Chelsea defence in one turn and City's record signing, Raheem Sterling, gave Ivanovic a torrid time throughout.
This was a plan masterminded to perfection by Manuel Pellegrini and executed to perfection by Aguero and co. A gameplan which awed the spectators and aesthetically pleased the analysts.
So, after subjugating Chelsea has City become the team to be feared the most in Premier League? With Toure back to his best, Aguero firing freely, Manchester United still finding their rhythm and Arsenal still looking for consistency, it certainly does look like City will be holding the trophy come May.
However, with two games gone, it is still early to judge the major title contenders, but if City are able to keep up the same tempo heading into February, then they are surely the team to beat in the 2015/2016 season.
