When I arrive at our training ground at Borussia Dortmund, everybody could hear just that a few seconds before I can actually be seen. Everybody knows it's me. I love to hear the machine working.

Achieving Champions League football is the minimum requirement and always the most important thing for [Dortmund Borussia] club. Beyond that, we want to win a trophy. Maybe the German Cup, because we've reached the last three finals, but haven't won one, so that's a big motivation for us.

Before I arrived here [ Borussia Dortmund], a lot of people were questioning about whether I could ever play as a striker, that I was a guy who could only run down the wing quickly.

I would love to have a race against Usain Bolt one day! It would certainly be a good challenge for me.

I want to score goals in every match, as many as possible.

Few years ago I did 30m in 3.7 seconds. Whether that makes me quicker than [Usain] Bolt, I don't know! We all know Usain is the best.

The mentality of coaches and players alike [in Bundesliga]. It's all about winning.
