I don’t get how he can be cool with getting punched in the face by Brian Clough in front of team mates, but can’t get over the fact SAF let him go at age 34 when he was pretty much finished. Absolute legend but I just don’t get it, I’ve forgiven people for worse things myself. The same personality traits he hates SAF for are the same things he does!
I think I can answer this one. I have certain similiar character traits to Keano (albeit, I'm not quite as intransigent).
Keane, above all else, values honesty and straightforwardness. That's evident in his punditry, in his team talks, in his book, in his style of football, in his style of management, in every fibre of his being.
What he doesn't value is prevarication, mealy-mouthedness, lies and being two faced.
When Clough punched him, that was just about as honest an expression of the manager's feelings as you can possibly get. There was no hiding behind words or saying things he didn't mean.
But when Fergie talked about "11 1/2 years", or being able to "sign for another club", or putting United first despite making some obviously nepotistic decisions... all of that was dishonest and a part of his usual mind games.
I'm a bit like Keane in the sense that I've forgiven some really serious stuff where the other person has been open and up-front, but held on to some minor grudges where I feel somebody has tried to manipulate me.
It's not so much pettiness, as it is standing up for what you believe in and being stubborn about not accepting what you feel is a basic trait of decency.
I'm nowhere near as bad as Keane, mind you. I've learned over the years to accept another person's cuntishness and just bottle up my feelings deep down. It's healthier that way.
