Football should never be a worry. It should be exciting. When a child plays football outside, he doesn't need to worry. Professionals should be the same.

There are some people who might have better technique than me, and some may be fitter than me, but the main thing is tactics. With most players, tactics are missing. You can divide tactics into insight, trust, and daring. In the tactical area, I think I just have more than most other players.

Speed is often confused with insight. When I start running earlier than the others, I appear faster.

It's disappointing to see how football, the world's No. 1 sport, is not No. 1 when it comes to development. It seems to me that a wealth of practical football knowledge is being squandered.

Tennis was more than a passing interest, but I found my ability didn't measure up to these West Coast kids who had played 12 months a year and taken it much more seriously than I.

I've found that there's a lot to invigorate in any country or destination - it's all about how you look at it. I've never really had any difficulties anywhere I've been. As an athlete, I used to enjoy being on the road and meeting people.

A good thing is I've been playing tennis I think every day for the last two months. I really haven't had a day off. I've been doing things that I did used to do.

The best football is always about expression of emotion. Always.
