Tottenham defender Vedran Corluka could find himself in trouble with the Football Association after clashing with a home fan following Saturday's win over Stoke.
Corluka came under fire from some fans after hitting an injury-time free-kick straight out of play during the 3-2 victory.
The Croatian international had to be dragged away from the fan by assistant manager Kevin Bond at the final whistle as tempers boiled over at White Hart Lane.
Corluka revealed he called the supporter 'an idiot' and he could be the subject of an FA investigation for his show of aggression.
"I told one supporter he was an idiot," said Corluka. "He was moaning during the match when he should have been supporting the team.
"I told him to support instead of criticising. But Kevin did not calm me down, I didn't need calming down."
Tottenham boss Harry Redknapp revealed he will have a chat with Corluka about the bust-up.
"I didn't see it. I wanted him to stick it into the corner for Gareth Bale but it didn't work. Players have to be careful in the current climate," said Redknapp.
"I'll speak to Corluka about it, but I don't understand why fans want to give one of their own players stick."
