Here's 9 of Keane's most famous quotes:
'Happiness is not being afraid'.
'When I first went to Manchester United, Bryan Robson was somebody I looked up to, still do. But I was young, and when you're young, you smell blood. It was like, 'Robbo, I'm after you, I'm taking you''.
'Patrick Vieira is 6'4", and he starts having a go at Gary Neville, so I said 'come on have a go at me,' that's it'.
'I remember having conversations about loyalty when I was at the club. I don't think he knows the meaning of the word. To constantly criticise other players that brought him success. I won't be losing any sleep over it'.
Keane talking about former Manchester United manager Sir Alex Ferguson
'It seems to be in this club (Manchester United) that you have to play badly to be rewarded. Maybe that's what I should do when I come back. Play badly'.
'I can understand the attraction of people wanting to go to London - if you are talking about Arsenal, Chelsea or Tottenham. But there are players going to clubs in London simply because it is London'.
'Will those on telly yesterday be remembered for what they’ve achieved ? None whatsoever. I wouldn’t trust them to walk my dog. There are ex-players and ex-referees being given air-time who I wouldn’t listen to in a pub'.
'I’m not at Manchester United to keep everyone happy'.
'Before the game there was all this stuff about anti-racism and anti-bullying. It would be a good idea to start wearing wristbands for anti-diving'.
