Other excerpts from Keane's book the second half

"There'd been a little bit of tension between us over the years,

for football reasons. He said, 'I've had enough of you. It's time we sorted this out.' So I said, 'OK,' and we had a fight. It felt like 10 minutes. There was a lot of noise - Peter's a big lad. I woke up the next morning. I kind of vaguely remembered the fight. My hand was really sore and one of my fingers was bent backwards. Anyway, Peter had grabbed me, I'd head-butted him - we'd been fighting for ages."

"I should have appreciated Real's offer more. It was the most attractive challenge in front of me but I didn't accept it. In hindsight, I should have said to myself: 'Go, go to Spain, live there for a year and a half, learn the language, learn the culture.' I took a negative approach. As much as anything else, it was fear that decided me - fear of the unknown."
