Wenger was once again critical of those Arsenal fans who have demonstrating against him during matches this season.
Planes carrying anti-Wenger slogans, boycotts of home games and signs and banners being displayed inside stadiums came during a blip for Arsenal which Wenger believes cost them dear.
“I’m in a public job, I accept to be criticised and people don’t agree with me,” he said.
“But once the game starts and you are a fan, you stand behind the team, that is what I have not accepted this season and I will never accept it.
“Outside of the game I never had any word with any journalist in 20 years when they criticised my decisions and it is the same with the fans.
“But when a game starts you support your team. We have played some games in a hostile environment and I never accept that.”
