I've worked really hard on getting into the box more and being closer to the goal, which I think has brought real benefits to my game. It's definitely improved my goal scoring.

I have a passion for fast cars. To drive them means pure joy to me.

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.

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.

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.
