QPR remain rooted to the bottom of the Premier League table following a shambolic showing where they showed little signs of organisation against United, relying on set pieces and physical play to trouble the league leaders.
Rafael da Silva was the star for the Red Devils after opening the scoring with a wondrous strike from distance into the top corner of the net and following it up with a goal-line clearance later in the first half. Ryan Giggs then doubled the lead for United in the second half after Nani did well to slip in a through ball to unlock the offside trap.
Julio Cesar - 7.5
The scoreline could easily have been much wide if not for the former Inter Milan custodian with his instinctive saves that denied Van Persie and Hernandez in the first half. There was little he could do about the two goals conceded.
Jose Bosingwa - 5
Bosingwa returned to the QPR starting XI after being benched by Harry Redknapp. He did little in supporting Mackie up front and did not impress at the back, allowing Young time and space to set play up.
Chris Samba - 7
Samba was a commanding presence in the air and dominated both penalty boxes at set pieces. He had a goal-bound header cleared off the line and another header that struck the post late in the game. His efforts in defence also helped Cesar from being overwhelmed.
Clint Hill - 4.5
The QPR captain was slow to most of the challenges - he lost track of Van Persie several times, allowing the Dutch striker to make runs behind him (including the one that led to Rafael's goal) and was lucky not to be booked for a high, late challenge on Rafael.
Armand Traore - 5.5
Traore had a decent game, partly because Nani kept on cutting in early instead of going down the flank. Traore supported his flank well and allowed Taarabt to push up.
Andros Townsend (Off 72') - 4
The Tottenham loanee was wasteful on the right flank whenever he had the ball, attempting ambitious shots and crosses way beyond his means. He was also frequently chasing back Evra's overlapping runs, to little success, even resorting to a deliberate-looking stomp on the United man's face.
Esteban Granero (Off 45') - 4.5
Granero saw little of the ball in the congested midfield, forcing him to go deeper to pick up the ball, where he then found his limited passing range not working for him. He was brought off at half time due to injury.
Stephen Mbia - 7
Mbia was a force in the middle for QPR and central to destroying United's play, although he could have easily have been booked several times in the first half for his roughhouse challenges on his opponents. He ability to win the ball helped QPR launch several counter-attacks and he was one of the brighter sparks in an abject QPR side.
Jamie Mackie - 3.5
Mackie was virtually anonymous in the first half and failed to contribute anything significant to his side.
Adel Taarabt - 3
Unlike Mackie, Taarabt saw a lot of the ball but he was extremely wasteful, being selfish with little result to show. He attempted a shot every time he looked up and found himself within 30 yards of goal, but the attempts ended up looking more like rugby field goals. He needs to learn to play as a team and not as an individual.
Bobby Zamora (Off 61') - 3.5
Zamora did not even manage a sniff on goal, although it wasn't entirely his fault as Taarabt kept on firing shots whenever the striker laid off passes to him outside the box.
Jermaine Jenas (On 45') - 5
Jenas came on for Granero and added more physical presence to the midfield, always trying to close down United's midfielders to little success.
Loic Remy (On 61') - 5.5
Remy looked livelier than Zamora and managed to test De Gea from open play for the first time within minutes of coming on. However, he had little chances thereafter when United started to close down the game.
Hoilett (On 72') - 5.5
The former Blackburn winger came on but saw little of the ball.
David De Gea - 7.5
The Spaniard kept his third consecutive clean sheet after a neat afternoon of work against a physical QPR side. De Gea wasn't really tested in the first half but reacted well when called upon later on.
Rafael Da Silva - 8.5
Rafael had an excellent all-round game and deserved to be named Man of the Match after his sweet strike that opened the scoring which is surely a candidate for Goal of the Season. He was solid at the back, helping to clear off a goal-bound header and immediately sent a sublime cross-field 60 yard pass to Van Persie on the counter attack. Probably the most improved United player this season.
Rio Ferdinand - 7
Ferdinand looked assured at the back and was there to sweep up the little threat posed by QPR's blunt attack.
Nemanja Vidic - 7.5
Vidic deserves praise after a whole match of aerial battles against the colossal Samba. The Serbian was outsized but he was certainly not outmatched in terms of determination and managed to put Samba off from winning more headers.
Patrice Evra - 7
Evra had little to do defensively, partly due to Townsend's ineffectiveness. Evra contributed well to the United attack and was part of the build up that led to Giggs' goal.
Nani - 8
Nani did his future prospects at United no harm with a tidy display which was not plagued by his usual showboating and horrid crosses. He looked confident on the ball and was more willing to play the short passing game, and improvement from the frustrating ineffective Nani that fans came to hate. He set up Giggs' goal with a smart turn-and-pass move.
Ryan Giggs - 8
It's hard to think how much more Giggs can contribute to United. The veteran midfielder was energetic from the start and won tackles that helped United launch counter attacks, including the one that led to Rafael's goal. He also picked up a goal for himself with a calm finish after his tireless running behind QPR's lines paid off.
Michael Carrick - 7.5
Carrick was literally bullied in midfield by QPR's plans to stop United from playing football but he adapted well as the game got on, pinging passes away before opponents could get near him.
Ashley Young (Off 66') - 5.5
Young had many chances to prove himself with chances down the flank but his delivery was disappointing and more often than not found a QPR player.
Javier Hernandez (Off 61') - 7
Hernandez would surely be frustrated with a goalless outing but he showed promise in terms of his play outside the box, frequently dragging Hill out of position.
Robin van Persie (Off 41') - 7
Van Persie's running behind QPR's defensive line was a constant source of trouble for them and it paid off as it led to Rafael's goal. He was brought off early after suffering a hip injury apparently caused by colliding with a camera.
Danny Welbeck (On 41') - 6
Welbeck looked bereft of confidence on the ball. He did well to get into good positions but frequently took too many touches to steady himself where a first-time shot would probably result in a goal.
Wayne Rooney (On 61') - 6.5
Rooney came on late for Hernandez despite not being reported as not fully fit for the match. He clearly wasn't at his sharpest but the run out would be encouraging for fans hoping to see him in action against Real Madrid at Old Trafford.
Antonio Valencia (Off 66') - 6.5
Valencia came on and slotted in on the right to press QPR further back but didn't contribute anything significant to the game.
