Former Manchester United captain Roy Keane has revealed that he once had a fight with goalkeeper Peter Schmeichel.
The altercation, which was refereed by the duo's United teammate Nicky Butt, took place in a hotel on the club's pre-season tour of Asia in 1998.
"I had a bust-up with Peter when we were on a pre-season tour of Asia, in 1998, just after I came back from my cruciate injury. I think we were in Hong Kong. There was drink involved," Keane wrote in his soon to be released book The Second Half.
"The manager had a go at us as we were getting on the bus, and people were going on about a fight in the hotel the night before. It started coming back to me - the fight between me and Pete.
"In the meantime, Nicky Butt had been filling me in on what had happened the night before. Butty had refereed the fight. Anyway, Peter had grabbed me, I'd headbutted him [and] we'd been fighting for ages."
Keane, who spent 12 years at Old Trafford, went on to reveal that the clash left Schmeichel with a black eye and also woke up club legend Sir Bobby Charlton.
"At the press conference, Peter took his sunglasses off. He had a black eye. The questions came at him 'Peter, what happened to your eye?' [Schmeichel] said 'I just got an elbow last night, in training'. And that was the end of it," Keane continued.
"The first day back at the training ground, the manager pulled myself and Peter into his office. He knew exactly where we'd fought - I think he mentioned the 27th floor. He told us that we were a disgrace to the club, and that we'd woken Bobby Charlton up, that Bobby had come out of his room and seen us.
"Peter took responsibility for the fight, which was good. I admired him for it. But Sir Bobby could have tried to break it up."
Keane is now the assistant manager of both Aston Villa and the Republic of Ireland.
