My foundation now has some 120 football pitches laid out for children, a lot of them immigrants. We live in a multicultural society.

This is the great crisis in football now. It's not just Rangers; it's a lot of clubs. Big clubs always create more debt despite the huge income they have. It's almost an achievement, isn't it? They make so much money, and yet, still, their debts rise and rise and rise. How does that happen? It's absurd.

The romance of English football is fantastic, but it has lost its identity under the influence of other cultures.

Ajax is a multicultural club, and we have found that many talented immigrant players quit when they reach puberty. So we wanted to tackle this problem with someone from the same background who had come through it. And that was Edgar Davids. During one of our fights, I pointed that out to him. But it had nothing to do with his skin colour.

Football is a game of mistakes. Whoever makes the fewest mistakes wins.

If you take golf, you have a teacher for the drive, a teacher for the approach play, and a teacher for the putt. That's three specialist coaches for one player. In football, one coach looks after 25 players.
