The Porto players were with me for two and a half years, they believed in me, in my methods, in the way we do it. The next day I go and a manager arrives who works completely differently.

I fell a bit in love with Celtic, because the atmosphere was amazing and the crowd was magnificent, the way they behaved with the Porto fans.

Football is a game based on emotion and intelligence. Anyone can be clever, the trick is not to think the other guy is stupid.

Unhappy is a nice word.

If I wanted to have an easy job, working with the big protection of what I have already done before, I would have stayed at Porto - beautiful blue chair, the Uefa Champions League trophy, God, and after God, me.

To me, attacking football happens when Makelele gets the ball and passes it to the central defender who passes it to the right-back who comes forward and judges the situation. If he can do something he passes forward or runs with the ball, if not he gives it back to Makelele who builds the attack again. That is attacking football. In England attacking football is giving the ball to Makelele and having him hit it forward no matter what, even if everybody is marked.

When I saw Rijkaard entering the referee's dressing room I couldn't believe it. When Didier Drogba was sent off, I wasn't surprised.
