I've learned so much from Mourinho and love being in his team and learning new roles.

It's not easy, especially for a German national team player who did great things in the past and maybe is struggling. That's why I think most of the German national team play abroad because if you don't play for Bayern Munich and you don't always win, it's difficult.

Of course I want to be on the pitch as much as possible and score goals for my club.

For a striker to come in and score his first goal is always important.

PKP' was a huge success, and even the sequel did well. I became very choosy after that.

What drives success, and the most successful students, is internal motivation.

Luxury is the wolf at the door and its fangs are the vanities and conceits germinated by success. When an artist learns this, he knows where the danger is.

I have no regrets about doing 'Strictly.' This is the biggest achievement of my life.
