Roy Keane: The Manchester United hero’s five most crazy incidents

3) International argument

While on international duty before the 2002 World Cup, Keane had enough of the unprofessionalism of the Ireland set up, and particularly with the manager Mick McCarthy.

He launched a tirade, saying “Mick, you’re a liar… you’re a f**king w**ker. I didn’t rate you as a player, I don’t rate you as a manager, and I don’t rate you as a person. You’re a f**king w**ker and you can stick your World Cup up your ar*e. The only reason I have any dealings with you is that somehow you are the manager of my country! You can stick it up your b**locks.”
