[Didier] Drogba sent me a text message after I won the African Player of the Year award. It made me very happy.

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

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

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

I've worked really hard on getting into the box more and being closer to the goal, which I think has brought real benefits to my game. It's definitely improved my goal scoring.

Few years ago I did 30m in 3.7 seconds. Whether that makes me quicker than [Usain] Bolt, I don't know! We all know Usain is the best.

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.
