Did everything that was asked of him when called upon, including a fine save from a Yaya Toure thunderbolt near the end of the first half.
The most unassuming of West Ham's midfield five, but supplied a sufficient support to the defense when the likes of Nolan and Morrison darted up field.
The makeshift left back was often found out of position in defense, while his decision making was at times suspect, but made strides going forward as he teamed up with Ricardo Vaz Te down the flank.
Was strong in the header and not afraid to venture forward when invited. Was caught out for Aguero's first goal but often found himself in the right place otherwise.
Should have done better for Aguero's second with the striker allowed a lot of space to head the ball home. Looked to be struggling as the game wore on in a fairly arduous display.
The man-of-the-moment was again lively for the hosts, bringing cheers from the crowd with a few neat tricks - including his lift over his shoulder for Vaz Te's goal - but his rawness at this level is still evident with his decision making at time suspect.
The captain was once again the heatbeat of all that was good with West Ham in the first half, although was perhaps lucky to be shown just a yellow card for a challenge. His influence started to falter in the second half as West Ham's grip on the game slipped.
Partnered brilliantly with Nolan in the center of the pitch, but his penchant to look for the Hollywood pass was to his side’s detriment at times.
Is still yet to find his form of last season but performed admirably against the likes of Yaya Toure. Was key to keeping Samir Nasri - who had a torrid game - quiet.
Completely anonymous in the first half, with Ricardo Vaz Te taking up the mantle on the left-hand side and Ravel Morrison catching the eye on the right. Grew in the second half as Richards started to tire but still not as effective as Allardyce would have liked.
Ricardo Vaz Té
As hard working and industrious as we have come to expect from the striker and was not afraid to go searching for the ball with West Ham up against it for the majority. Scored a terrific overhead kick from such harrying, before being taken off shortly afterwards.
Has been the subject of much critique of late, but wasn’t really even given the opportunity to impress with City so dominant and West Ham sloppy in the final third.
Showed signs of rustiness in the opening stages of his first Premier League outing this season, but grew into the game. Started to tire in the second half and looked at times at as if he was possibly being too stretched by the likes of Vaz Te, but impressive overall.
Solid, but nothing more. Struggled at times with Morrison but won the battle overall.
More fine work from the center back. He commanded the defense - which was completely changed from the last outing - with maturity. Comfortably first-choice in Pellegrini's eyes.
Often seen as a weak link in defense for City, but coped well against a relatively toothless West Ham attack.
Delightful to watch. With Yaya Toure making the space, Silva was filling it. Linked up well with Aguero and showed all his balance and skill for his goal late on.
Offered little-to-no attacking threat and was equally lost when backtracking. Out of character considering his recent form, and a display he will be keen to forget soon.
More of the highly polished, all-round impressiveness from the midfielder who was the hard-working ying to Silva’s yang. Was unlucky not to notch a goal after finding a pocket of space 18 yards from goal.
Was perhaps outshone by Silva and Yaya Toure, and is definitely not as eye-catching, but had a job to protect the back four and spot the odd forward run - and did it.
Continually found space and filled space, and was Aguero’s workhorse of a right-hand man. A brilliant piece of on-the-spot decision making saw him allow the ball to pass through his legs for Aguero’s first. A fine display.
In sublime form. Was hungry from the off and finished off both goals with aplomb. Linked up extremely well with Alvaro Negredo and David Silva all game. The standout performer.
