Roy Keane: In quotes

In his own words

KEANE SIX MONTHS BEFORE LEAVING FOREST FOR UNITED IN 1993: "I like Nottingham. It's a bit like Ireland. My heart is with this club"

KEANE IN HIS AUTOBIOGRAPHY: "Aggression is what I do. I go to war. You don't contest football matches in a reasonable state of mind"

KEANE TO MICK MCCARTHY: "You were a crap player, you're a crap manager. The only reason I have any dealings with you is that somehow you're manager of my country, and you're not even Irish"

KEANE ON ENGLAND: "I wouldn't watch a whole England game but I see the highlights"

ON CORPORATE FANS: "Some people come to Old Trafford and can't spell football, let alone understand it. They have a few drinks and a prawn sandwich but don't realise what's happening on the pitch"

KEANE AFTER A DEFEAT: "Rolex watches, mansions, garages full of flash cars, set up for life. Forgot the game, lost the hunger that got you the watches, cars and mansions"

KEANE ON MOTIVATION: "People ask where my competitive streak comes from. It's fear. I have a big fear of failure"

KEANE ON ALAN SMITH: "What is [Alan Smith] doing there? He's wandering round as if he's lost. He doesn't know what he's doing"

KEANE ON RIO FERDINAND: "Just because you're paid £120,000 a week and play well for 20 minutes against Tottenham, you think you're a superstar"

How others see him

RYAN GIGGS, TEAM-MATE: "He's mad, but funny too"

RORY MCGRATH, 'THEY THINK IT'S ALL OVER': "Keane says he'll stay at United through thick and thin, or Posh and Becks as they're known"

NED KELLY, FORMER HEAD OF SECURITY: "Socialising with Roy was always a pleasure until that one drink too many"
