Tomasz Kuszczak - A strangely quiet afternoon for the Pole, who conceded two goals despite facing almost no shots in open play.
Fabio - Another fine shift at right-back, and the youngster's attacking instincts and determination prompted the penalty which completed United's turnaround.
Chris Smalling - One or two nervy moments in the first half, but superb after the break against West Ham's sporadic raids. Came close to his first league goal with an early header which Green tipped over.
Nemanja Vidic - A welcome return for the skipper, who enjoyed mixed fortunes. He was perhaps harshly deemed to have fouled Cole in the box, but may also have seen red for a foul on Ba.
Patrice Evra - A quiet outing from the Frenchman, who uncharacteristically conceded a cheap penalty and then made way at half-time as United chased the game.
Antonio Valencia - Magnificent work in the first period especially, giving Wayne Bridge a torrid time, and played an incisive pass to Rooney for the Reds' equaliser.
Darron Gibson - Booked in the first period for lashing out in frustration, Gibbo maintained important patience and discipline in the second period and underpinned United's approach play.
Michael Carrick - Chanced his arm from distance on a couple of occasions, but was integral to United's patient approach play in the second half.
