Arsene Wenger hit back at his critics after Arsenal fans chanted 'you don't know what you're doing' towards the end of the goalless draw at Aston Villa.
Supporters launched their attack on the Gunners boss after he replaced Olivier Giroud with Francis Coquelin with two minutes remaining. Wenger refused to comment on that outburst or why he made the change but he was in a fighting mood when asked about the chants in his post-match press conference.
He said: "I don't want to comment on that. I do my job and do my best for the club. I leave it to you to judge. I try to be as good as I can be."
