"We are both passionate about this club, but it was a mistake. I am sorry," the Togolese striker was quoted saying on the club's website.

"We should have been more calm during the game and although I was pleased to get a goal back for the team when I came on, I am sorry for the disagreement with my team-mate Nicklas," added Adebayor.

The Danish striker had to quit the game and was seen with a cut on his nose. The FA has requested the tape to view the incident and both players are expected to banned.

The Gunners have also opened an inquiry. Captain William Gallas had to intervene to contain the situation but said that he doesn't know the reason behind this incident.
