Arsene Wenger has praised QPR midfielder Sandro.
Arsenal beat QPR 2-1 at Loftus Road to keep the pressure on Chris Ramsey's side at the bottom of the table.
Speaking to the club's official website, manager Arsene Wenger admitted his side showed nerves in the first half as they struggled to get to grips with the game.
He also took time to credit QPR midfielder Sandro having to be substituted as a pivotal factor in their narrow victory.
Wenger said: "I felt that we were nervous and they put a shift in in the first half physically. They paid for that certainly in the second half.
"They stopped us from playing all over the pitch. Sandro played a big part in that and he had to come off after an hour - maybe it was easier for us to put the ball down and play after that."
Sandro has played only nine games since signing from Tottenham last summer, and this was his first Premier League appearance for QPR since November 23rd.
He lasted just 55 minutes before having to be substituted, struggling for fitness. Within 15 minutes Arsenal were 2-0 up, with Olivier Giroud scoring in the 64th minute, and Alexis Sanchez the 69th.
The Brazilian was playing in place of the suspended Joey Barton in midfield, and during his time on the pitch, managed tw tackles and three interceptions.
Whether Arsenal would have broken QPR down had he remained on the pitch at full fitness is another matter, but his display and Wenger's comments will be of huge encouragement to him personally as he bids to get his season going and save that of his club.
