Edin Dzeko's opening goal looked to have been cancelled out by Cheikh Tiote's fine effort but the midfielder's strike was controversially ruled out for offside. Alvaro Negredo netted late on to seal three points for Manuel Pellegrini's men.
In Sunday's other Premier League fixture, Liverpool and Stoke played out an eight-goal thriller as Luis Suarez scored twice in a 5-3 win for Brendan Rodgers' side.
