Arsene Wenger will launch a stern defence when he faces up to a UEFA disciplinary charge next week but could be facing heavier sanctions after blasting Europe's governing body as arrogant and a "dictatorship".
The Gunners manager and midfielder Samir Nasri have been charged for "inappropriate language" towards Swiss referee Massimo Busacca after the final whistle at the Nou Camp, where Arsenal lost 3-1 to Barcelona and crashed out of the Champions League after having striker Robin van Persie controversially sent off on Tuesday.
Wenger responded by saying: "The only thing that people remember is that the sending off killed the game. A bit more humility would do UEFA some good. To apologise for what happened would be much better than charge people who have done nothing wrong."
Busacca caused uproar by showing Van Persie a second yellow card for shooting at goal just one second after he had blown the whistle for offside - the Holland forward claimed he had not heard it due to the noise of the 95,000-plus crowd. Wenger confronted the Swiss official after the final whistle over the sending-off and angry exchanges continued inside the tunnel.
UEFA, who could yet take further action following Wenger's latest blast, will hear the disciplinary case on March 17.
The whole incident has overshadowed what was a fine performance by Barcelona, who dominated possession as Arsenal failed to muster a single shot on goal.
There have been suggestions Wenger swore at Busacca, who is reported to have not held back either. The Arsenal boss, though, would not divulge any firm details of the alleged exchanges.
"I will keep that for UEFA if they really want to know because I will have some interesting statements to make about some statements made by people who were not supposed to say what they said," he said.
"You can check any statement I made on television after the game. If I have done anything wrong I am ready to be charged.
"As for what is said in the tunnel, if you can get just one [time] where I have come out on what has been said against me or against the referee [in a tunnel] during my 15 years in England, I will pay for you to have a big holiday."
