I used to play as a striker in Holland. I grew up as a striker. That's the position I want to play.

If the vision is not right and if the right group of players is not together, it doesn't come together.

I like to explore the world.

From every little territory I've been, I've picked something up, things that I could use to better my game, to take with me, and the rest I left behind.

For a lot of different reasons I didn't fulfil my potential.

For every player it's nice to go to the World Cup and it's very important to do that in your career.

I feel confident that I'm good enough to play a lot of games for Liverpool.

I don't go to church every week.

If you don't believe you will end up as nothing. But if you believe a lot you can create a lot.

Some people think they do it all by themselves but I believe there is more to it. I believe it is God who has given me the talent and the opportunity to be successful.

I was loved in Liverpool, I had good relationship with the fans and my team-mates but I felt I could do better.

I left Liverpool through the back door.

I do have a weakness for Liverpool and I do want them to be champions.

The striker role, together with someone else, is pretty good for me.

If it fits in with my career, it will be a challenge for me to play for a MLS team. If that would be Steven Gerrard's club, that would be very special.

America has always been a special place for me, since my youth.

Yes, there is a lot of competition for places at Liverpool but that's the same at every top club. It was like that when I was at Ajax and that isn't a problem for me.

There are plenty of players who have a lot of talent. It's all about getting the best out of yourself and you'll have to work very hard to achieve that.

I have enough confidence at the moment to say that I have the potential to play at the same level as Arjen Robben or Franck Ribery.

Playing as a striker is a nice role because I spent all my youth there so that's why I like it.

Moving to Liverpool was a new world for me. I had been living with my parents in Holland, and all of a sudden I was living in a foreign country on my own.

Rafa Benitez promised me a certain development, but very quickly he took away that promise and it was a totally different situation.

I don't think people in England ever saw the best of me.

For a player to really be at his best you have to give him a certain confidence, but I did not feel appreciated by some people at Liverpool.
