Manchester City were very strong for the first ten minutes. With Cahill taking the injured John Terry's place, Chelsea are less intense and more vulnerable to short diagonal movements between Cahill and his full-back. This meant David Luiz was the left centre-back, a position he's much more used to and where he's most effective.
Chelsea's plan was obvious, apparently drawing inspiration on Sporting's display in the last Europa League tie against City: drop back with two banks of four and let Torres take full advantage of his newfound happiness, with Meireles as the link-up man. In fact, the Spaniard was very good working the channels, but the Portuguese is clearly not cut out for this position, since his decision-making is not always that good and he is not the most proficient player with his back to goal.

Even though Meireles was not offering a decisive contribution offensively, he was being successful at (almost) man-marking Yaya Touré out of the game. With the Ivorian stationed next to De Jong, Meireles' task was clearly to break up City's build-up play. Silva was missing and Touré had too many defensive duties. Mancini's furious reaction on the touchline was a clear proof that City were getting nothing out of the game.
For the second half, Mancini brought on Gareth Barry for Balotelli, proving that less (attackers) is sometimes more. With the centre in good hands, Yaya Touré could finally break free and tread onto Chelsea's comfort zone - which meant Silva and Nasri were able to play farther up front, too. In turn, Meireles wasn't sure whether he was supposed to keep closing down Yaya Touré or stick to Barry.
The goals had something of a chance factor in them. Chelsea's goal came from a deflection off Yaya Touré's leg and City's penalty was a desperate shot that hit Essien's arm. Apart from that (Nasri's mentioned effort aside), there were no clear-cut chances for either side and City's victory, while deserved, almost didn't happen. In the end, Mancini's gung ho approach - with Tévez, Dzeko and Agüero - proved too much for Chelsea. Nevertheless, Di Matteo's team is now more calm and collected, better organized and even Cech looks now like his old self, much less prone to mistakes and distractions.
