Generally safe under the high ball and pulled off a few saves when Norwich went forward late on.
Beaten a few times down the outside but a typically energetic performance going forward and put in a great cross for the fourth goal.
Was not stretched by Van Wolfswinkel and was able to spray balls around from defence.
Spent most of the evening in the Norwich half supplying crosses and linking up for one-twos. A good assist for Mata and his delivery also prompted the penalty.
Placed one second-half header over the bar and was physically dominant in challenging for the ball in his own half.
Executed a simple plan; got down the outside to deliver balls into the box and assisted Mata's second.
Still suffering a lack of confidence as his head tended to drop when he lost the ball but definite signs of encouragement in this display.
Signs of adventure in Carrick's play as he was often available in the final third for one-twos and through balls.
Scored two and could have had plenty more as a number of efforts tested Ruddy. Commanding display from the England man.
Worked hard and linked well with the likes of Kagawa and Valencia. Unlucky not to have scored with a snap volley and his smart movement yielded the penalty.
Impressed coming off the left wing to create the play. Conjured plenty of chances with one-twos and runs in behind.
Norwich's best player made a number of excellent saves and deserved better than to be on the end of a hiding.
Pinned back by a combination of Jones and Valencia and was exposed defensively as United got in time and again. Hit the bar late on.
Did not get to Rooney quickly enough for that crucial second goal and also let the ball slip by him for the penalty.
The concession of the penalty kick set United on their way as he was caught on the wrong side of Welbeck.
Nodded away plenty of clearances and made some important blocks in his box.
Provided whatever counter-attacking threat Norwich could muster.
Gave away too many balls in the centre of midfield to hand the initiative to United and blazed one over the 90th minute.
Neat and tidy on the ball but was involved all too infrequently.
Not afraid to get close to his striker and smashed in one goal which was disallowed.
A strong midfield presence in the first half, he got his foot in often but became all too passive as United took control.

His disaster of a season continued with another anonymous display.
