It looked pretty wild, but I was actually in control of myself. I've never really injured anyone throughout my career.

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

I am firmly convinced that you shouldn't necessarily emphasize hedonism, especially at the beginning of a career, but should instead focus entirely on performance.

I was so obsessed with football that you could say I was taking the goal home with me at night. And then one day the system fell apart.

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.

Goalkeepers need an element of insanity.

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