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 moment my name was called [Africa's Footballer of the Year] was truly overwhelming and I was about to scream with joy.

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

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

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

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.

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.
