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

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

It was Thomas Tuchel's first season as coach and I played centrally always. The whole team had a great year, one that I enjoyed a lot. Our style has changed a bit, from trying to score within five seconds to a more calm and in some regard more educated style of play. We try to find the right moment - and then we explode.

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

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

Before I arrived here [ Borussia Dortmund], a lot of people were questioning about whether I could ever play as a striker, that I was a guy who could only run down the wing quickly.

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.
