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.

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

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.

[Didier] Drogba sent me a text message after I won the African Player of the Year award. It made me very happy.

Last season I scored 27 goals but still lost out against Robert Lewandowski. This season has started very well for me, but again I have some tough opponents, most notably with Anthony Modeste from FC Koln. I texted him the other day: "Keep calm, my friend." I am happy for him to be so successful. And in a certain way it even helps me. The better the other strikers are, the more I have to work to be to be ahead of them.

I always set myself new goals. I always want to do better than I did in the past. I always want to achieve things I never achieved before.

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.
