Every goal is hard work, especially in such an excellent league as the Bundesliga; or even take the Champions League.

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.

At the same time the players around me almost make it an automatism to score goals. We have so much quality and speed on the pitch - the genius of players like Mario Gotze or Marco Reus has to lead to goals.

I've played in France. There, in many matches everybody is already happy if he can secure a point. Here, in Germany? Forget it! Everybody wants to win. The last-placed team in the standings would take any match with the ambition to win it. That makes it so hard, even for the best teams in the league.

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.

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

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.
