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.

There have been miraculous stories in the history of big football events all around the globe, with host nations achieving fantastic results and even winning titles with the support of their fans.

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

At Milan when I was younger, I worked a lot on the leg press because I'd lost a bit of my natural speed as my body was changing. I was growing too fast for the rest of my body to cope and I had some knee problems. I worked really hard in the gym to regain these fast sprints.

I would love to have a race against Usain Bolt one day! It would certainly be a good challenge for me.

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.

There are a lot of things to like about [Borussia Dortmund's fans] and the city of Dortmund as a whole.I like their honesty. And I like that my family and I can feel safe here. I don' t have to worry at all about my safety and their and my own safety. Believe me, in other countries I have made different experiences in that regard. All of this, too, has led to my decision to extend my contract until 2020, and I can imagine staying even longer.
