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.

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

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.

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.

With [Samuel] Eto'o, I talked a lot about his great career and how I could become a better player.

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

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.
