The 31-year-old is enjoying one of his best spells at Old Trafford and has agreed to sign a new two-year contract at the end of the season. Carrick lauded the efforts of his team to claw out the result after the runaway Premier League leader moved 15 points clear of second-place Manchester City thanks to a stunning Rafael opener and a second-half Ryan Giggs goal.
"We expected a tough game and we certainly got it, especially in the first half. The pitch was bouncy and bobbly and it's tight at the best of times here [at Loftus Road]," Carrick told MUTV after the game. "It was just a case of adapting to the conditions and the context of the game, battling it out at times. I thought we did that well.
"Sometimes you have to do that. Throughout the season it's not always going to be pretty. Sometimes you have to grind out results, work hard and make the most of your opportunities.
"We were able to cope with QPR and, at times, we played some good football. At other times we defended well and played on the break. In the second half we controlled the game and created more chances.
"All in all I think we can be delighted with how the day's gone."
Carrick also reserved praise for the center back pairing of Nemanja Vidic and Rio Ferdinand, who started together for the first time since the 1-1 draw at Tottenham on Jan. 20.
"You know what you're going to get [with Rio and Nemanja],” Carrick said. “They know each other's games inside out, and with me in front you have that little triangle that we use to try and defend well and start counterattacks from.
"It was a case today of doing the basics right and letting the front boys produce the quality. As it turned out it was Rafa who produced the quality.
“It could have been more in the end, but we'll take what we got."
