Life is too short not to celebrate nice moments!

When I left Dortmund, I said it's not important what people think when you come in but what they think when you leave.

Anyone can have a good day, but you have to be able to perform on a bad day.

The challenge is to stay cool enough to handle the pressure in the moment so that you can succeed in the future.

I am not a dreamer. I am a football romantic.

If you want special results, you have to feel special things and do special things together. You can speak about spirit, or you can live it.

It needs time. Nobody wants to hear it, but that's the truth: if you want to have success in the future, you have to be ready to work now.

It's not about changing people; it's sometimes about changing a situation. How can we build an even better situation for them?

I have only one understanding of development and of making success, and that's by going step by step.
