The fans of Borussia Dortmund are truly amazing. It is hard to describe what you feel when you play in front of them, the atmosphere they create not only on the yellow wall with its 25000-something fans jumping up and down a full 90-plus minutes of every game, no matter the score or the opponent.

Only Bayern Munich really have some sort of a guarantee to win if they only catch a good day. All the others need really good days to win. I like that.

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.

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.

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.

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

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.
