We have our ambitions [in Dortmund Borussia], and of course I would love to win some titles after some years of finishing second or losing finals.

The mentality of coaches and players alike [in Bundesliga]. It's all about winning.

Only Bayern Munich really have some sort of a guarantee to win if they only catch a good day. All the others need really good days to win. I like that.

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.

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.

The moment my name was called [Africa's Footballer of the Year] was truly overwhelming and I was about to scream with joy.

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