The boss believes Giroud has improved a lot during his two-and-a-half years at the club but says the striker can raise his game even further.
“He had an important part in a game as direct as that, to keep the ball, to close them down,” Wenger told Arsenal Player. “Overall he had a great contribution. I’m happy for him.
“[Between] when I brought him here, and [when] you look at him today, I think there’s a hell of a difference.
“That’s credit to him - to the player he was and the player he is today, plus credit for his whole season, where he has worked very hard. I think there’s still room for improvement for him.”
