You know, there has never been a watershed moment with a coach when I've gone, 'Wow, I learned something today.'

My career has been the best part of 50 years. If I had to go through it all again, I'd love to, warts and all. There have been so many good things that they outweigh the bad. But I do have regrets.

There's managers out there now who would love to have won a single trophy. The fact is the vast majority of them haven't. So I'm quite cool about what I did as a player and as a manager. Could I have done better, or differently? Of course. But that's all water that has flowed under the bridge; it doesn't cause me any sleepless nights.

The world's best when I was growing up was Pele and he would have been a great player now, too, but Messi surpasses him.

I can remember Bob Paisley was never happy.
