“Real Madrid offered me a year and a half deal,” Keane recounted in his second autobiography.

“Michael (Kennedy) had been over to Madrid and he’d negotiated a deal with Real. They spoke to me, too. Butragueño rang me. Emilio Butragueño – what a player he was. Michael had given me a heads-up that Butragueño would be phoning, so I took my mobile everywhere with me.

“And – how’s your luck – he rang me when I was sitting on the toilet. He said, ‘Look, Roy, we’ll be glad to have you.’ The club’s board just had to sanction the deal; it was standard procedure.

“I was going, ‘–okay’, hesitating. Michael was going, ‘What are you doing, Roy?’”

“It was the most attractive challenge in front of me, but I didn’t accept it,” he said.

“With hindsight, I should have said to myself, ‘Go. Go to Spain, live there for a year and a half, learn a different language, learn the culture. You might end up loving it. You might even stay there.’

“I took a negative approach, I think, instead of saying, ‘This is amazing, what a chance for me.’ It could have been great for my kids. The weather and the training might have given me another lease of life, another two years of playing; I might have picked up new techniques for my stretching. But instead – as usual – I was looking at what might go wrong. ‘Hindsight’ is a fucker of a word. At the time, it felt like the right decision.”

“I didn’t want to move to Spain. As much as anything else, it was fear that decided me – fear of the unknown. And I threw excuses in front of me – family, language, the kids’ education. I could imagine myself going to Madrid, and into the dressing room. I’d be starting all over again, and I was in no mood to be doing that. I’d had a tough career. Physically, I was struggling.

“It’s no good playing for a club; or, it’s not just about playing for them. It’s about having an effect on the club, having a big influence. That was one of my concerns when I left United. I was thirty-four, an experienced player. Real Madrid might just have wanted someone to do a job, sit in the middle of the park for a few games. But I wanted to go in and have an effect on a team.”

“Forget about Madrid, Everton, Celtic, Barcelona, Inter Milan and the reasons I should or shouldn’t have gone to any of them. The fact is, the morning I left United I lost the love for the game a little bit.

“I could have had every club in the world ringing me but it wouldn’t have given me that buzz, that satisfaction, that ‘Here we go’.”
