I remember my last game for Newcastle in the pre-season, when their fans were singing that they wanted me to stay, but when the opportunity came to play for a great club like Liverpool with such a great history, I had to take it. I hope they understand why I made that choice to go to Liverpool.

You always learn from a defeat, even more than when you win games, because when you win, you don't see everything you did wrong.

As a player, I have this feeling - and I think every player thinks this - that I am responsible for how my team-mates feel. I just want to do my best and give 100 per cent, and if I do that, they will feel better and think, 'I will give 100%.'

Liverpool is a great club.

I am happy at PSV, but I am a player with a lot of ambition.

It's irrelevant how I prefer to play and what I want. It's all about what works for the team.

You will always learn from games. But every game is not the same, not the same emotion.

I wanted to be a gymnast when I was young - I used to do backflips and all those things in the street and at home - but my grandma said it was dangerous and made me stop.

Before I signed for Liverpool, I was playing for Newcastle as a No. 10 - basically, I was always attacking. I didn't have to do much defensive work; I didn't play as the No. 6 or the No. 8.

At Newcastle, I was playing in the No 10 position but also in midfield as a left winger.

When you lose games, you analyse them more than when you win.

Every team learns when they lose a game.

I don't want to leave Feyenoord before having made an impact at the club.

I want to move to one of Europe's best clubs if I leave Rotterdam, just like Robin van Persie and Kuyt did before.

It would be absolutely fantastic to play at Real Madrid together with my friend Royston Drenthe.

You must play with the same intention: to win the game and give everything you have.

You can't afford to lose games. It is always possible that you will not win, but it is the way you play the game.

I like to score goals, as, back in the day, I was used to scoring goals.

Every player wants to score more.

It's my dream to play in a big league, and England would be the perfect choice.

To follow in the footsteps of Dirk Kuyt would be sensational. He triumphed at Feyenoord and has had great success at Liverpool.

It's always a blow for a team if important players get injured or suspended.

With my quality, I feel I can bring a lot to a team that I will join. I want to show it in the big leagues: England, Italy, Spain, Germany, and France.

When a lot of players come to a club, it can be difficult to gel because you don't know each other properly.

When it goes bad, you know supporters will be angry at players who were bought for most money.

It's not normal to score four goals in a game.

Everyone in the Champions League has quality.

I was always happy to play for the Dutch national team.

Some days, you don't score, but then you have to make sure you don't concede.

You don't always have to win beautiful.

Liverpool will always buy good players, even if they already have good players. That's normal. I think it has to be normal for a club like Liverpool because that means you're a big club.

I always try to perform, and not because you have players on the bench or on the pitch that can play in your position.

Learning to play different roles has made me a more all-round midfielder.

It makes it easier for you to play more often and it makes it easier for the manager if he has players who can be used in different positions.

I think I've shown I have the defensive discipline to play deep as the No.6 and start the build ups with my passing. I can also play higher up the pitch and make a difference in the opposition area. Being able to do both has helped me to play so many games.

I have to be honest: in my career, I've really had to fight to come in the middle again. A lot of managers told me, 'You are way more comfortable as a winger than as a midfielder,' but I always kept my trust and confidence in what I knew about my qualities.

Because I was fast, technical, and could dribble well, it was always the easy thing to label me just a winger and have me stick to that.

At seven, I played centre-back. When you're so young, though, it's more to enjoy the training and to get a feel for the game. It's not heavy on tactics of a position. We were playing on a half pitch, seven against seven or eight against eight, so they say you're a centre-back, but it's not like the real definition.

At Under-11/12, I was playing as a right-back. The manager then was Cyril Helstone, and he said to me, 'No, you're not a defender. You should be in midfield.' That was the big change in my career because from that moment until I made my debut in the first-team at Feyenoord, that was the position I played.

I think Anfield is a fortress.

Sometimes you need luck to score.

When you play at home, you want the fans behind you, and you must give them something back.

I think, a lot of teams, when they come to Anfield and they play a draw, they think it is a good result.

I can play in different positions, and if I can do what I'm good at, score goals, show how good I can play football, then it's OK with me.

If a whole team doesn't perform, you cannot pick one player especially and say, 'He doesn't do this or do that.'

It is a fault of the whole team if you don't deliver.

If you look at the difference games between the bigger and smaller teams, the difference in concentration, and being passive is big; that is my opinion.

I don't care what other people say about me. I know what I'm capable of.

Normally, I am a player who can play in different positions, but never in defence.

You're always disappointed when you lose a game.
