I train for one-and-a-half hours every day in order to keep my energy level high.

You have to work more than your adversary.

We can only win by giving everything and being ready to defeat the adversary with fiery aggression.

The player can only compete with the best internationally when they've committed themselves to this goal. They have to be properly supported until that point.

We coaches have to learn how to deal with that: How do I get to each one best - with a talk, with video analysis? And what sort of tone? We need our own coaches for that. The sports psychologist coaches me too.

Personally, I need a high level of physical fitness in order to feel at ease.

I had to delegate authority to the people on my staff. That means you shave away the hierarchy.
