Largely untested in a match that City dominated. Solid and commanding on the rare occasions he needed to be.
Such an adventurous presence down the right flank, always providing width and impetus. Never breached and always dangerous himself.
The Argentine was criticised in the formative months of his City career, but has improved immeasurably and stood up to the test of Carroll well and matched West Ham's physicality blow for blow.
Motored down the left wing with menace, though struggled to pick out a killer final ball and was a little too ambitious with some of his efforts on goal.
Wrestled and tustled with Carroll well, showing his brute strength, and stepped up on the ball with authority. A captain's performance was topped by a poacher's effort at the start of the second half.
Showed little of the bombastic power he is noted for, but was instead a calming and serene presence in the heart of City's midfield. Provided an assist for Nasri and controlled the game.
Such an elusive figure, ghosting into space and gliding beyond West Ham shirts with such ease and trying to unpick the deep defence. Saw a deflected effort smash the angle of the bar.
A maligned figure for much of his time on Manchester, but was a destructive, commanding figure for City. His height was especially useful.
Always on the move, making sniping, dangerous runs, and it was the Frenchman who found the telling breakthrough with a stinging drive into the far corner.
Returned from a brief lay-off to partner Dzeko upfront. Offered some of the movement and penalty-box presence City have missed, but otherwise starved of chances, appeared to lack sharpness and spurned an open goal.
Has been in sensational form recently but only ever lurked on the periphery against West Ham. The ball never stuck with the Bosnian, much to the frustration of his team-mate.
Performed a couple of acrobatic, spectacular saves but was at fault for Nasri's opener, failing to get a strong enough hand to the ball.
Largely stood up to the test of City's forward line well, making telling blocks, interceptions and clearances, but couldn't resist the might of the home side's attack for the entirety of the match.
Out of contract in the summer and will hope a solid display against the champions can merit a new deal, having largely coped with City's right flank well.
Relatively untroubled with no direct man to mark, though that was less true when Kolarov overlapped. Never shied away from getting on the ball.
Perhaps West Ham's most dominant player in the air, and made some important interventions from pull-backs and crosses. Though, along with his team-mates, looked unusually unsteady at set-pieces.
A leggy, powerful runner, but City's overwhelming possession forced him back, deep into his own half. Tracked back to good effect though, frustrating the hosts.
Struggled to get in behind City or feed targetman Carroll. Even in one-on-one races with the normally sluggish Demichelis he was unable to come out on top.
One of few West Ham players capable of unlocking City's defence and looked assured when on the ball, unlike his team-mates. Worked hard to try to close down City but his efforts were ultimately futile. Booked.
Visibly frustrated by City's dominance - and rightly booked for a late challenge on Hart - and struggled to impose himself on the match. Unsurprisingly subbed.
Made a thorough nuisance of himself whenever possible, barging, buffeting and brawling with City's back-line. Certainly tried his best to aid former club Liverpool, even deflecting Silva's shot against the bar.
