David de Gea 7 - effective rushing from his line to clear danger and almost saved Aguero's second goal. Was left woefully exposed for the opener.
Antonio Valencia 6 - completely bypassed for the first goal of the game but improved from there, getting forward well to support the attack.
Phil Jones 6 - like most of United's defence, Jones endured a torrid start to the game but eventually steadied himself, making some vital stops.
Chris Smalling 7 - slightly more composed than Jones defensively and scored the fourth goal, taking his close range header well to wrap the game up.
Daley Blind 6 - was caused problems by Zabaleta and Navas early on, but was fairly steady. Some may say he was out of position for City's second goal.
Michael Carrick 6 - stopped tracking Silva's run for the opener when someone of his experience should know better, but kept possession well after that.
Ander Herrera 7 - continues to impress, and whilst he didn't get himself on the scoresheet again, he was clever with his passing and controlled midfield.
Ashley Young 9 - one goal and two assists; you can't really ask for much more from a winger. Young's rebirth under Louis van Gaal has been key to United's recent resurgence.
Juan Mata 8 - calmness personified when through on goal to make it 3-1, slipping the ball underneath Joe Hart with aplomb. Becoming a big game player for United.
Marouane Fellaini 9 - City just couldn't handle him at all. The Belgian pulled onto full backs and centre backs and beat all of them in the air, scoring the second goal at the back post with a fine header.
Wayne Rooney 7 - played a nice ball to Mata to make it 3-1 but wasn't as influential as United would like. Had bright moments but not at his best.
Marcos Rojo, Angel Di Maria and Radamel Falcao all came on late into the game, but weren't on long enough to make an impact on the game - especially considering that the game was over as a contest when they entered the fray.
