The Netherlands international started the game on the bench, but entered the fray at 1-1 to score the decisive goals for the Emirates outfit.
With Van Persie now carrying the bulk of The Gunners’ goal-scoring responsibilities, the French coach was full of praise for the match-winner.
“Leaving a player like Robin out is always a risk but medically he needed a break,” Wenger told Sky Sports.
“We knew we could have 20 to 30 minutes without that risk and he used that time well. He has fantastic quality and when you look at his record it’s remarkable.”
Arsenal started the Premier League slowly, but have started to put a revival together, and Wenger feels his side are improving with every game.
“It was an important game for us. You could see we played well and played with spirit.
“Our fans are behind the team completely again after a difficult period because they see that the team plays with a fantastic attitude. Our quality is improving from game to game,” he concluded.
Wenger’s men face a test to see how far they have come next weekend, as they travel to Stamford Bridge to take on London rivals Chelsea.
