The Gunners host Bayern Munich in the first leg of their Champions League showdown on Tuesday night just a few days after crashing out of the FA Cup at home to Championship Blackburn.
Reports on Monday morning suggested that despite the Gunners facing up to what could be an eighth season without a trophy, negotiations had already started with Wenger over a new deal, his current set to expire in the summer of 2014.
However, Wenger, 63, went on the offensive at his pre-match press conference, looking to set the record straight.
"That is the wrong information and I work for 16 years in England and I think I deserve a bit more credit than wrong information that has only one intention: to harm," the Arsenal boss said.
"If it is good information which comes from nowhere it is all right, but this is wrong information that comes from nowhere and it is completely wrong."
Wenger then became involved in a heated exchange with a journalist, adding: "I look at you not because you give information, I do not know if it is you, I do not know where the information comes from. Why do you look at me? I just thought you had given this information out.
"Here this is a pre-match conference for the Champions League, if you want to talk about Saturday, that press conference has been made after the game. Can we get some questions about tomorrow's game, that would be very nice."
