Gareth Barry produced an impressive performance against West Ham United to help Manchester city secure a vital win. City took a deserved lead when the superb Yaya Toure fired past Robert Green from Gareth Barry's cut-back.

And they made it two at a subdued Upton Park as Yaya Toure's shot hit a post and went in off Green's back.

Adam Johnson rounded Green to seal the points before James Collins headed a consolation for rock-bottom West Ham.

The result sees big-spending City leapfrog Chelsea and Manchester United to join Arsenal on 32 points, although the Gunners' goal difference is superior by five.
