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.

I was always sure the Bundesliga was the right choice for me. My first season was solid, if unspectacular, so maybe I would have preferred it not to be so hard at the beginning, but I've worked very hard to get to this point and want to get even better now.

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

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

I try to stay as young as these rookies are.It feels a bit strange not to be anymore the youngster I used to be. But I'm okay with it. Mostly, I enjoy being on the pitch with so many talented players around me.

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.

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.
