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

There have been miraculous stories in the history of big football events all around the globe, with host nations achieving fantastic results and even winning titles with the support of their fans.

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.

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.

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.

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

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.
