Mark Hughes believes QPR can surprise Manchester United on Sunday if they put in a similar performance to that shown against Arsenal last weekend.
Sir Alex Ferguson's side come into the Old Trafford clash looking for an eighth successive Barclays Premier League victory, although the Hoops' aspirations are at the other end of the table.
QPR are running out of games to stave off relegation but head to the north west on the back of a morale-boosting 2-1 victory against Arsenal, and Hughes said: "The three points was the main thing but the pleasing part from my point of view was the manner of the performance."
He added: "I think from start to finish it was a good, solid performance and we had a good understanding of what we had to do to go and get a result against them.
"The lads went out and performed to the letter so really, from my point of view, we have to keep on replicating that and the application that we showed.
"The determination to see the game through to its conclusion was there for everybody to see so if we show that in the games we have remaining we will pick up more points, which is obviously the order of the day."
Hughes will again be without Djibril Cisse for the trip to Old Trafford through suspension, although he can call upon DJ Campbell and Heidar Helguson once again.
Both strikers have been sidelined for more than two months, but top scorer Helguson returns from a groin injury and summer signing Campbell is back after a hamstring problem.
"They are in the squad and are available," he said. "They have obviously had more work this week and they are an option.
"DJ is probably a little more ahead than Heidar because he has had a couple more weeks training, but they are both available."
