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.

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.

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.

Most of all I hope the tournament [The 2017 Africa Cup of Nations] will help unite our people [in Gabon]. My wish is to celebrate a big party all together.

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.

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

First and foremost, we have to focus on what we're doing and not worry about what Bayern - or any other clubs - are doing.
