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.

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.

Achieving Champions League football is the minimum requirement and always the most important thing for [Dortmund Borussia] club. Beyond that, we want to win a trophy. Maybe the German Cup, because we've reached the last three finals, but haven't won one, so that's a big motivation for us.

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

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.

With [Samuel] Eto'o, I talked a lot about his great career and how I could become a better player.

The fans of Borussia Dortmund are truly amazing. It is hard to describe what you feel when you play in front of them, the atmosphere they create not only on the yellow wall with its 25000-something fans jumping up and down a full 90-plus minutes of every game, no matter the score or the opponent.
