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.

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.

Football is not about suffering. It's about enjoyment. Control the ball, be friendly with it, try to attack, try to score goals. Of course defending is part of it, but you can defend in a lot of ways.
