David de Gea 7 - West Brom offered little threat today, and the Spaniard made just three saves, but whatever he had to do, de Gea did it well.
Rafael 8 - the Brazilian almost got on the scoresheet with a back post header that forced a stunning save from Ben Foster, and Rafael continued to get forward throughout, as well as being solid defensively.
Chris Smalling 8 - Smalling started in his natural centre back position, and had a great game, showing athleticism and a reading of the game that will make many believe he is the future replacement for Rio Ferdinand.
Phil Jones 8 - Jones had a terrible start to the game as he looked slow and ponderous in possession, but grew into the game, scoring the opening goal and forming a strong defensive partnership with the aforementioned Smalling.
Patrice Evra 7 - Evra had a decent game as he got forward and defended fairly well, though Baggies winger Morgan Amalfitano gave him some trouble at times.
Michael Carrick 8 - Carrick was key in protecting the youthful centre back partnership, and kept thing ticking over - as he usually does - with calmness in possession and accurate passing.
Marouane Fellaini 9 - Another great display from Fellaini, who bossed the game in all areas of the field. He was strong but also creative in possession, and formed a strong midfield partnership with Carrick.
Adnan Januzaj 7 - the youngster came in and out of the game, but got an early knock following a strong challenge from Amalfitano, and struggled to really excel after that.
Juan Mata 8 - Mata had one of his better games in a United shirt today, with only Fellaini having more touches than the former Chelsea man. Mata was always looking to create and looked busy in attack.
Wayne Rooney 8 - Rooney capped off a good display with a fine back post header that wrapped up a win for Moyes' men. Once again, Rooney was always looking to create and thoroughly deserved his goal.
Robin van Persie 6 - Another difficult game for the Dutchman, who was lucky to stay on the pitch following a rash challenge whilst already on a booking. Was unsurprisingly hauled off with half an hour to play.
Danny Welbeck 7 - the rangy striker offered more than van Persie in his short time on the field, coolly slotting home the third goal having been played in on goal.
Shinji Kagawa 6 - Kagawa failed to really get into the game as he touched the ball just 19 times, but only came on with 15 minutes to play.
Nemanja Vidic - the Serbian came on with just three minutes to play and wasn't required to do much defending with the game already sewn up.
