David de Gea 7
Solid when called upon -- mostly in the second half -- but overall didn't have a great deal to do. Distribution not perfect.
Patrice Evra 6
Unsurprisingly not as spectacular as Rafael on the opposite flank, but it was a reassuringly steady performance from old Patrice.
Chris Smalling 6
Looked a little shaky with his positioning early on, but recovered to play pretty well. The powerful Victor Anichebe was disruptive with his pace and strength, but Smalling managed to keep him mostly under control.
Phil Jones 7
Looked as defensively solid as Smalling, and capped his performance with a nice headed goal in the first half. It's pretty clear that his best position is at the centre of defence, where he gets to kick a football as little as possible.
Rafael da Silva 9
United's man of the match. Rafael was imperious down the right hand side; supreme both defensively and venturing forward -- rattling the crossbar with a great header in the first half. A fantastic performance after the horror show that was Smalling at right-back against Olympiacos, capped with a great assist for Rooney's goal.
Marouane Fellaini 8
What a surprise: Fellaini isn't so bad after all! In fact, it's clear that the Belgian is United's best central midfielder, and one who fits into David Moyes' system excellently. Not afraid to drive into the box to provide an attacking threat, he was a constant handful for the West Brom defence. A valuable asset.
Michael Carrick 6
Just about the classic Carrick display, in which he passed the ball and didn't do a great deal else. That isn't a criticism per se; it did, after all, allow Fellaini to break forward, but it wasn't a spectacular performance either.
Adnan Januzaj 6
Another bright display from United's resident wonderkid, who impressed down the left -- though was slightly less sparkling than usual. Only Ben Foster's crossbar prevented Rafael from converting his perfect ball into the box in the first half.
Wayne Rooney 7
Rooney was typically frustrating in the first half, appearing to play too close to van Persie and failing to effectively link United's midfield and attack. That improved in the second, with his performance topped by an excellent headed goal.
Juan Mata 6
*Copies and pastes rating from every one of Mata's other United matches.* Oh, he managed to get back for a goalline clearance, too.
Robin van Persie 6
Delivered a nice cross for Jones' opener, but was otherwise fairly anonymous.
