Arsenal forward Robin van Persie accused former strike partner Emmanuel Adebayor of a "mindless and malicious stamp" during Manchester City's 4-2 win over the London club at Eastlands on Saturday.
"We are both professional footballers and I know that the game is physical, I too have made hard and sometimes mistimed challenges but never with the intention of hurting an opponent.
"He set out to hurt me today. He has shown a real lack of class," the 26-year-old added.
Speaking to Sky Sports after the match Adebayor said there was no intent on his part to hurt his opponent and that any contact had been accidental.
"I did not have time to take back my feet," the Togo international said.
"Because I was trying to kick the ball my feet touched his head. At the end of the game I told him I'm very sorry."
Adebayor also apologised for running the length of the pitch to celebrate in front of the visiting Arsenal fans the goal he scored in City's victory.
That earned him a booking and he told Sky Sports: "I shouldn't have done what I did but the emotion took over me and I'm sorry for what I've done."
