"I try to maintain control, try to stay calm. But the red mist sometimes descends - and once that happens 50,000 people would not be able to stop me bursting into a fit of rage."
- Keane, after being sent off against Newcastle in 2001.
"If Roy has said he might play for Ireland again then someone must have caught him just after he'd had his Christmas pudding."
- Alex Ferguson's response to rumours that Keane was considering playing for Ireland again.
"The telephone hasn't stopped ringing all day with reporters looking for my opinion. The only ones who didn't ring were Reuters and that's only because they're busy in Iraq."
- Jason McAteer on the day Keane announced his return to international football.
"Sometimes you wonder, do they understand the game of football? Away from home our fans are fantastic, I'd call them the hardcore fans.
"But at home they have a few drinks and probably the prawn sandwiches, and they don't realise what's going on out on the pitch.
"I don't think some of the people who come to Old Trafford can spell football, never mind understand it."
- after the 2000 Champions League game against Dynamo Kiev.
"How many chances should a player get? You can bring a horse to water but you cannot make it drink."
- Keane on Ruud van Nistelrooy.
"They say Al Capone did some good things. Trouble was, he would go out in the streets and shoot people. Keane is becoming Manchester United's Al Capone."
- Brian Clough after Keane was sent off for a lunge on Manchester City's Alf Inge Haaland.
"Maybe Gary Neville deserves to be chased up a tunnel every now and then - there'd be a queue for him probably - but I think you have to draw a line eventually."
- Keane on his encounter with Patrick Vieira after the Arsenal man picked on little Gary in the Highbury tunnel.
"I was sent off for pushing him (Alan Shearer) - but if you're going to get sent off, you might as well punch him properly. It's the same punishment. You might as well get hung for a sheep as a lamb."
- after yet another brush with the Newcastle captain.
"Barring a personality transplant, his only job at Old Trafford will be as a player."
- George Best, suggesting that Roy Keane hasn't quite got what it takes to become manager of Manchester United.
