The Football Association has fined Arsene Wenger £2,500 and the Arsenal manager has been warned as to his future conduct following comments he made to the referee at half-time in his side's 2-2 draw against Portsmouth.
Wenger had admitted a charge of improper conduct in relation to his words and behaviour towards Steve Bennett on 16 December.
The Gunners boss was sent to the stands by the referee and commented after the draw: "I was sent off because I complained about a foul on Gael Clichy which was not given.
"I complained in the tunnel at half-time to the referee and he sent me off. I do not remember being sent off before, but I went and sat in the stands where the assistant referee told me to go in the second half."
After being charged, a disappointed Wenger had said: "I arrived ten years ago and believe me I have seen ten times worse than what happened on Saturday.
"I was amazed I was banned from the touchline in the second half, considering what I have seen in the corridors the last ten years.
"I will not accept any charge on that incident. I feel that strongly about it.
"I find it quite scandalous considering what I have seen in the corridors the last ten years, it is difficult to explain and accept.
"I think I am big enough to say when I am wrong and big enough to accept it, but on this particular incident I don't accept what happened."
