Goals from second half substitutes Mario Balotelli and James Milner ensured City overcome a defensively good Everton in a 2-0 win.
With David Moyes's side keeping Manchester City at bay brilliantly for an hour, Roberto Mancini's decision to leave the unhappy Carlos Tevez on the bench paid dividend's when the Italian Balotelli opened the scoring.
Everton, who have won on their last four previous trip's to Manchester City, started the brighter and Maroune Fellaini caused Joleon Lescott problems early doors, however they failed to test Joe Hart in their dominant period
Jack Rodwell did a good man marking job on Manchester City's David Silva, and with the Spaniard being marked out of the early proceeding's, the pressure was on Samir Nasri to take ahold of the game, however the former Arsenal player was quiet as City failed to create any clear cut chances in the first half.
Manchester City came out of the blocks quick in the second half and Sergio Aguero was starting to get more into the game, however it took the change of Balotelli for them to open up a resolute Everton.
Consistant pressure from Mancini's side resulted in the opening goal as Aguero kept ahold of the ball to find the Balotelli whose shot took a little knick of Phil Jagielka giving Tim Howard little chance in the Everton goal.

The win for Manchester City was a deserved one and shows the club has the character and patience to break down sides who are going to come and try and frustrate sides at the Etihad Stadium.
