Arsenal midfielder Jack Wilshere was delighted to get 70 minutes under his belt to mark the end of a 'long journey' back from injury.
He said: "We didn't underestimate QPR and knew they were going to be strong, especially from midfield and the wingers."
Wenger took Wilshere off for Theo Walcott after 70 minutes and the midfielder admits it was the right decision, having experienced cramping as the match wore on.
"The boss spoke to me this morning and said to see how I feel after 60 minutes," he said. "I was cramping up after 60 so it was better for Theo to come on fresh.
"To be fair he made a difference, pushing down the side to let Mikel (Arteta) go further forward and get the win."
The youngster says fellow midfielders Arteta, who netted the winner in the 84th minute, and Santi Cazorla guided him through his first game back.
He said: "The older players and more experienced players here like Mikel and Santi helped me through it and I thank them."
