A low key afternoon for the England goalkeeper. Off his line quickly but did struggle under one high ball. Helpless to prevent Rooney's goal.
One slight mistake with virtually his first involvement in the game but imperious thereafter. Too much desire and power for the United forwards and superb reading of the game to snuff out danger early.
A typically understated yet almost flawless performance from the right-back. Did his job defensively with no frills and always looked to get forward.
Perhaps harshly booked for a robust aerial challenge with Smalling but very solid for most of the game. Alert to read the danger when United pushed forward and showed a good understanding with Kompany.
The Serbian has faced questions of his defending but handled Valencia comfortably and was superb overlapping Nasri and delivering crosses into the box. And it worked perfectly with his whipped in cross for Aguero's opener.
His pace on the right side always offered the hosts an attacking option, and he made it count once United started chasing the game. Superb run and cross to set up Nasri's strike.
Dominated the midfield and comfortably won his battle with Fellaini. Clever passing, awesome athleticism and a goal to his name, turned over the line from close range on the stroke of half-time.
Very intelligent display from the Frenchman as he drifted inside, linked up neatly in midfield and looked to find Kolarov on the overlap. Deserved his goal - a perfectly placed volley in the 50th minute.
Sat in midfield and comfortably dealt with United's threat in between the lines. Simple and efficient use of the ball to set the platform for the more creative players.
The Spaniard was on the periphery early on but grew in stature and was key in the crucial second and third goals. Glancing header from a corner fell for Toure to score before sharp turn and cross set up Aguero just after the restart.
A decisive double for the Argentine striker as he produced two excellent volleyed finishes. Broke the deadlock with an improvised left-footed hooked volley in the 16th minute and added his second with his right-foot after escaping the attention of United's defenders.
The Spaniard could only look at his defenders and ask what on earth they were doing as City tore United apart. Could do nothing about any of the hosts' strikes.
Made some strong challenges in the opening minutes but then joined the rest of United's back four in spectator mode. Didn't get close enough to City's strikers in the penalty area.
Caught ball watching amid City's clever movement and roasted for pace by Navas for the fourth goal. Hit the post with a late header at the other end.
Failed to get his head down and run at the City defenders until United were already four goals down. Booked for dissent after seeing a penalty appeal waved away.
Never got to grips with City's attacking threat, most notably leaving Aguero completely unmarked for the third goal.
Involved in a head clash early on and maybe it did something to his senses. Could not handle Kolarov's overlaps and kept losing Nasri, not least for the Frenchman's goal.
Dreadful during 52 minutes on the pitch in which he continually misplaced passes and crosses and offered Evra little defensive support.
Outclassed by Toure in central midfield for most of the game, the Belgian looked more threatening when he played as a second striker with the game already beyond United.
Some accurate passing as ever but he lacked movement in front of him and was immediately put under pressure by City's midfielders.
Made a couple of dangerous runs in the first-half but his decision making was poor in the final third. Worked hard throughout, both in a central role and off the left.
Looked sharp but endured a deeply frustrating afternoon until a brilliant free-kick provided the smallest of consolations. Booked for persistent offences in the first-half and needed more support as he was forced to play off scraps.
