ARSENE WENGER has vowed to fight UEFA following the threat of a new disciplinary rap. The Arsenal boss hit back after learning officials are investigating whether he passed instructions to his players from the stand during Tuesday's clash with Udinese. He was serving a touchline ban imposed following last season's tie in Barcelona which ruled that out. Wenger said: "We are completely open to any inquiry. We have nothing to hide and we do not think that we've done anything wrong."Frankly, you never know what a manager's ban is. "I did not communicate with the bench. I did watch the game from the directors' box. That was quite enjoyable. That's it. "We had spoken to UEFA prior to the game. That's why I'm quite surprised they need an inquiry. "They gave us rules and we observed strictly what they told us. After the game, or during the game, the rules changed." UEFA rules stated Wenger was banned from communicating directly with his players during his side's 1-0 Champions League play-off victory. The club claim they got approval from UEFA before kick-off for him to communicate via a third party. But at half-time they were told he had to stop talking to first-team coach Boro Primorac. And Wenger learned yesterday that UEFA will meet on Monday to discuss new proceedings against him for 'not abiding by the decisions of UEFA's control and disciplinary body'. Wenger refused to be drawn on whether UEFA were guilty of double standards, given its lack of action over Jose Mourinho's behaviour following the Spanish Super Cup on Wednesday. Mourinho jabbed a Barcelona coach in the eye after his Real Madrid side's 3-2 defeat but has so far escaped without punishment. Wenger added: "I don't want to go down that route. I tried to behave properly. If it's not right, I'm not going to look at other people. Just myself. "I knew the rules were not clear. We tried to get them from UEFA before the game and we behaved according to what they told us." UEFA's decision is expected before the Gunners' return leg at Udinese on Wednesday.
