At Milan when I was younger, I worked a lot on the leg press because I'd lost a bit of my natural speed as my body was changing. I was growing too fast for the rest of my body to cope and I had some knee problems. I worked really hard in the gym to regain these fast sprints.

My mother used to have a shop in which she offered very colorful clothes. I liked that from my early days on.

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

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.

There are a lot of things to like about [Borussia Dortmund's fans] and the city of Dortmund as a whole.I like their honesty. And I like that my family and I can feel safe here. I don' t have to worry at all about my safety and their and my own safety. Believe me, in other countries I have made different experiences in that regard. All of this, too, has led to my decision to extend my contract until 2020, and I can imagine staying even longer.

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

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.
