Veciferous handball claims come from West Ham players, as Jarvis crosses in with the ball deflecting off Zabaleta just inside the penalty area. No spot-kick given by Webb though.

The tempo decreases as West Ham push forward, but as Diame crosses long for Carroll, Zabaleta gets his head on the ball and steers it out for a throw-in.

After checking back to avoid tangling with Zabaleta, Jarvis launches a right-footed cross towards the far post but such is the pace of the delivery that it bounces out of play.

Toure can't feed the ball through to Tevez as Collins steps up, before Reid slides in illegally on Silva as City win a free-kick on the right side.

Chris Green writes: 'Both of these teams may have nothing to play for, but I am still expecting this match to be a cracker, if they both play to their potential. It would be great if West Ham caused a major shock here but I think this will be a bridge too far for them.. My prediction for today's game: Man City 3-1 West Ham.'
City boast a handsome record against the Hammers, with only one defeat suffered in their last 11 Premier League meetings, seven of which they've won. However, West Ham's Andy Carroll is coming good towards the end of his loan spell with Sam Allardyce's side, and many will fancy his chances of opening the scoring at 10/1 or bagging any time at 7/2 with Sky Bet. Indeed, the former Newcastle striker has scored four times against City, more than he has managed against any other Premier League team, so there's certainly value in those prices.
David Silva returns from a three-match absence with a hamstring injury to make his 100th league appearance for Manchester City. Sergio Aguero is also available for the Blues, who have Joleon Lescott in defence in place of Matija Nastasic. West Ham have secured Premier League safety following their return to the top flight under Sam Allardyce last summer and are unchanged from the team that beat Wigan last weekend, with in-form Andy Carroll up front.
West Ham: Jaaskelainen, Reid, Nolan, Jarvis, Carroll, Vaz Te, O'Brien, Collins, Demel, Diame, O'Neil. Subs: Henderson, Taylor, C.Cole, Collison, Noble, Pogatetz, J.Cole.
Man City: Hart, Zabaleta, Kompany, Lescott, Clichy, Yaya Toure, Barry, Silva, Tevez, Nasri, Aguero. Subs: Man City subs v West Ham: Pantilimon, Kolo Toure, Nastasic, Kolarov, Garcia, Milner, Dzeko.
