Roy Keane is one of a kind. I don't think there's anyone like him out there. There was a rumour long time ago that after a game, Peter Schmeichel stood up in the dressing room and started talking aloud to everyone. Then Roy Keane just went up to him, smacked him one and told him to shut up. From then on everyone knows that he's got control of the dressing room, and no one was gonna mess with him. Then of course there was the famous tunnel incident with Vieira.
Rooney can definitely become future United captain. As for England, couldn't give a toss. However I do think that Rio deserves it more than Terry, simply because Terry is a kunt.
How did Ronaldo get to become Portugal captain anyway? Queiroz must have let all that United success get to his head. It's one reason why Portugal is failing atm. Ronaldo is magic, but not one to inspire and lead a team.
