Of course, success is a relative term. It can be something completely different from winning the German championship eight times or making millions.

After a decade in a club it's quite normal and necessary that you seek and take a new challenge.

It's part of my game to occasionally send a message, one that may be unpopular to the outside world, but can be important for the team.

I want to successfully make the transition from a life in professional sports to another life, without running into major upheavals.

It took me a long time to realize that football isn't martyrdom, but a game that's enjoyable, and one in which getting better at it is supposed to be fun. Perhaps it would have been better if I had understood this as a young man.

Complaining and arguing will not help. We are fully concentrating on the game against the Czechs.

After the 2006 World Cup, I knew that you don't always need success, success, success on the pitch.

I have a feeling we are going to be world champions, I can't really explain why. Brazil are probably the best team in the world in terms of individual players. But the team with the most gifted players do not always win.

Big matches on the big stage are often decided at the back.

I've never really seen myself in the role of the victim.

The goalkeeper plays in a psychological position, and he's dealing with mental things. I wanted to describe the things I've done wrong and, most of all, what I've done right, so that other people, including those in other professions, could learn from my experiences.

If I play, I try to concentrate on producing my best.
