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.
"Is it hurtful? Look, I have managed for 30 years at the top level and I have to convince you I can manage the team?
"How many games have you managed? I promise you if you manage one I will sit in the stands and chant 'you know what you are doing!"'
When questioned about the substitution, Wenger said: "You can discuss every substitution. You think what you want.
"I do my job and I let people judge it. I do that every day and I do my best every day. I know why I do it.
"What is the thinking behind the substitution? I will not explain every decision I make, you judge the game for the papers and I sit here and explain to you our game.
"You are all great managers! I read the newspapers every day and I can tell you that you are always great managers!"
Wenger denies his reluctance to explain his substitution will cause a rift with Gunners supporters.
He said: "Why should I create a rift? I have given you the answer."
