David de Gea
Given little to do all afternoon and not at fault for the goal. Met a few crosses with confidence.
Unlucky not to score early on in the second half but will be unhappy to have conceded.
The engine in the United midfield and gave the more attacking players a platform to roam forward. Professional display.
Quiet going forward but never troubled defensively. Will face more difficult afternoons over the festive period.
A constant menace down the right flank and set up a number of assists for his team-mates. Possibly should have scored one himself, as well.
Linked up superbly with Valencia down the right and was acting as more of a winger at times.
A very impressive display and looked composed on the ball throughout. Not afraid to get forward and will also be unhappy not to have kept a clean sheet.
Involved in a lot of United's play and linked up will with Rooney in midfield. His form has picked up of late.
Took his goal brilliantly and troubled the opposition all afternoon. Brought off by Moyes to save him for upcoming games.
Ran the show in the centre of the park and was given far too much space all game. A really accomplished display from the talisman.
Scored the opener to and assisted the second. Showed glimpses of further brilliance before being taken off with an injury. A quality display.
Would be harsh to criticise the stopper for any of the goals on his debut. Pulled off a fantastic stop early on to deny Cleverley.
Will be glad to see the back of Januzaj. The youngster gave him a torrid time all afternoon. Struggled.
Beaten on both occasions for the opening two goals and struggled to cope with United's attacking players.
Was given the unenviable task of dealing with the United's forward threat and made no glaring errors, though the forward line looked comfortable on the ball throughout.
Physical when required but often wasteful with possession when his side needed composure.
Was never scared to let the opposition know that he was there. Lacked composure when it was needed. however.
As willing as ever but often overran in midfield by Rooney, Cleverley and Jones. Battled until the end.
A quiet afternoon. His manager will have been looking for him to provide an outlet but he saw little of the ball.
Replaced early on in the second period without making too much of an impact. More fight needed.
Seemed the only West Ham player with any genuine attacking threat. Saw a lot of the ball against his former club but was given little help elsewhere.
Struggled to replicate his midweek heroics even with the odd show of class.
Brought on late in the game and failed to make too much of an impact.
Given a good half an hour to help his sides' fortunes but failed to do so. Fought a losing battle against a rampant United midfield.
Introduced in the second half and showed great composure to pull a goal back.
