AC Milan captain Gennaro Gattuso has apologised for losing his cool in his side's Champions League defeat on Tuesday.
Tenacious midfielder Gattuso was involved in several incidents during the Italian giants' 1-0 home defeat to Tottenham, which means Milan will need to win at White Hart Lane to make the Champions League quarter-finals.
The game became ugly when AC Milan's Mathieu Flamini only received a yellow card for a crude two-footed lunge on Tottenham's Vedran Corluka, who had to be substituted.
Gattuso traded words with Tottenham's assistant manager Joe Jordan before shoving him in the face. Tempers flared again after the final whistle, with Gattuso head-butting the Spurs coach.
The retired Italy international had to be restrained by team-mates and escorted down the tunnel. He is expected to face a sanction from UEFA.
"I lost control," Gattuso told reporters after the match.
"There is no excuse for what I have done. I take my responsibilities for that."
"I was nervous. I didn't want to argue with players and I did it with him, but I was wrong to do what I have done."
Spurs manager Harry Redknapp did not want to comment on the incident at the post-match press conference, but was quoted as telling The Daily Mail: "He picked on the wrong man there. I know who I'd pick between Joe and Gattuso anyway ... Joe all night long."
Redknapp believes the incident showed Milan were 'rattled' - a fair achievement for a club who are making their first appearance in the Champions League.
"Milan lost their heads at the end there - they were rattled, for sure - and I guess that's a good sign," he said.
Gattuso also picked up a yellow card in the match, meaning he will miss the second-leg clash at White Hart Lane on March 9 regardless of any UEFA punishment.
