Agreed, they'd both do anything to win. A sublime player / manager combination.
I was at his 1st old firm game at Ibrox after he signed for Celtic, he was about 50% fit, 34 years old, but still best player on the pitch. He was immense. Pass, move, pass, move, winning all his tackles. Kept the game simple, his experience and quality got him through the intensity of that game, despite being only half fit. Celtic won 1 nil. Wayne Rooney was in with the Celtic fans that day at Ibrox. He actually sat quite close to me. Keane was undoubtedly a World Class footballer in his prime. Can't believe some football fans think he was bang average. All he did was hit people with tackles etc. Utter nonsense. Guy would have gotten in to any team in World football in his prime.
Sure Real Madrid as well as Celtic wanted him. Keane actually spoke to Emilio Butreganio ( not sure on spelling ) who was like a sporting director. Imagine Real Madrid wanting to sign you at 34. Says it all. He chose Celtic as, emotionally, Celtic is very hard to turn down for an Irish person. The bomd between Celtic football club and Ireland is well known.
I was at "an Evening with Roy Keane" last July in Cork and he said at that, that the lure of playing in the old firm derby was too hard to resist.
I have to say I absolutely loved him as a player and still do.
