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.

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

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.

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.

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.

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

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.
