At the German FA, they don't like criticism.

I was always proud, and still am, to wear the BVB jersey and to be part of this exceptional team.

When the big clubs, and Manchester United is one of the biggest clubs in the world, is interested in you, it's an honour and it's a kind of an acceptance of what you play - so it's a good thing.

Not everyone can win the European Championship.

We can't all play forever.

I know how strong Klopp's teams are.

I rather win one championship as a key player than four championships as a part-time player.

When I end my career, I don't need to win eight championships, I'd rather have done something special.

Nobody thought that I could become a professional. I was not that good. It was really just one thing I had fun doing. But it was never realistic for me to become a professional until I became 17 or maybe 18.

You don't often find a team where people are really friends with each other.
