Speed is a part of me. I think I was born with that, and nowadays a fast player, I need a fast car, too.

I try to stay as young as these rookies are.It feels a bit strange not to be anymore the youngster I used to be. But I'm okay with it. Mostly, I enjoy being on the pitch with so many talented players around me.

There are a lot of things to like about [Borussia Dortmund's fans] and the city of Dortmund as a whole.I like their honesty. And I like that my family and I can feel safe here. I don' t have to worry at all about my safety and their and my own safety. Believe me, in other countries I have made different experiences in that regard. All of this, too, has led to my decision to extend my contract until 2020, and I can imagine staying even longer.

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.

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.

At the same time the players around me almost make it an automatism to score goals. We have so much quality and speed on the pitch - the genius of players like Mario Gotze or Marco Reus has to lead to goals.

We have our ambitions [in Dortmund Borussia], and of course I would love to win some titles after some years of finishing second or losing finals.
