I know Robin van Persie very well and he is a great person and I have a lot of contact with him over the phone and text messages.

A return to the Eredivisie would be nice, but only if it's Ajax. I don't want to play for another team.

It doesn't annoy me that I always get asked about my future.

My career's been a bumpy road, but at the same time I think I am living proof that if you put enough work into things you decide more or less where you want to end up.

We can't all be Lionel Messi, even if we want to.

Music has always been an important part of my life.

If you see my record I'm not a stereotype killer striker.

With Ajax and Liverpool, you win about 80 per cent of matches.

I've done so much in my career but a little part of me feels I still have unfinished business here in the Premier League.

During your career, you have to make decisions. Sometimes maybe you don't make such a good decision and at the end you have to try and recreate a position.

If you see the kids now they have attitude and a strong character. They play one or two games and demand they are involved. I didn't have that. I was too polite. It is not maybe always good to have fight, but gives a stamp - it shows directly that 'I am here. I mean business.'

I've said in earlier interviews maybe I should have stayed one or two more years in Holland.

Before I take an offer seriously, I do my own research.

I think the 20-year-old me from that time, if I could have been managed under Jurgen Klopp, I'd have benefitted.

I would be so proud to finish my career with a European medal.

When you can win with a couple of goals, it is always really good for confidence.

I've tried to work as hard as possible.

I tried to go to places I'd enjoy playing.

I just have to try to be patient, keep working hard and doing my best.

I enjoyed my time in Germany, I definitely rate the league as it develops well and you have quite a lot of teams that play good football.

I do think I have a thing or two to improve myself although it is difficult to reach your full potential at an average team.

I still believe I can be a striker but, if you want to be a striker, you have to think more about yourself and that's why you are a striker.

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.

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

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

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.

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

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.

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.

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.

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

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.

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

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

I left Liverpool through the back door.

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

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.

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

I don't go to church every week.

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

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

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

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.

I like to explore the world.

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

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

At Harvard, I grew up a lot in terms of being able to deal with different types of people because where I grew up in Arizona, it's predominately white and predominantly Mormon families, so there's not a whole lot of diversity.

Coming to Harvard was an eye-opening experience because there's so much diversity on campus.

Any way that I can help the Harvard football program and Harvard is great.

I don't see myself being able to stay away from football.
