Arsenal's Arsene Wenger has been fined £15,000 and "severely reprimanded" by the Football Association for comments about Ruud van Nistelrooy.
He was found guilty of an improper conduct charge for accusing the Manchester United player of 'cheating'.
The Gunners manager denied the charge, but told Arsenal's official website he would not appeal against the decision.
"Now is the time to move on. We have an important match coming up and all my thoughts are focused on that," he said.
Wenger was not present for the hearing in central London, but was punished in his absence, with the FA also warning him as to his future conduct.
The controversy arose from Wenger's television comments after Arsenal's 2-0 defeat in October at Old Trafford.
He said of the Dutchman: "We all know him, he can only cheat people who don't know him."
Wenger's initial comments were made in the heat of the moment on television in
the aftermath of a title clash that his side had lost 2-0, ending their record 49-game
unbeaten league run.
Wenger was also investigated by the FA over comments he made about referee Mike Riley's decision to award the penalty.
The FA also looked into reports that food was thrown at United manager Alex Ferguson in the tunnel after the game.
