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

In football you never know, but generally speaking, I feel more than comfortable here [in Borussia Dortmund]. There' s no place on earth I'd rather be.

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.

Every goal is hard work, especially in such an excellent league as the Bundesliga; or even take the Champions League.

I've played in France. There, in many matches everybody is already happy if he can secure a point. Here, in Germany? Forget it! Everybody wants to win. The last-placed team in the standings would take any match with the ambition to win it. That makes it so hard, even for the best teams in the league.

Didier Drogba and Samuel Eto'o, two fantastic African footballers. So successful. And very nice characters as well. I got the luck to know them personally. They helped me a lot.
