#4. Roy Keane on Mick Mcarthy
Manchester United seem to be making a habit of developing great players with great character with even greater chances of expressing their opinion when they want to. Not many people would cross Roy Keane because of his intimidating personality.
He was never afraid to say what he thought which was also the reason he left Manchester United. He has even lost his temper against Sir Alex Ferguson on more than one occasion in the dressing room.
But probably his biggest outburst was when he let his temper get the better of him against former Ireland coach Mick Mccarthy. Here is what he said:
“Mick, you're a liar... you're a f****g w*****r. 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******g w*****r and you can stick your World Cup up your a***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******s.”
