It was a great experience under Van Gaal. He gave you the confidence to go and play.
He moulded me as a player by teaching me the basics, the fundamentals of football, and definitely made me the player I was until I stopped playing. That is what Van Gaal does.
If you look at most youngsters, they have worked well under Van Gaal. I had never heard of Thomas Muller at Bayern Munich before Van Gaal managed him, and he's now one of the best players in the world.
When you have Van Gaal in charge, it is a fact that there is fear in his team. The players have a fear for mister Van Gaal. That is not always good.
Van Gaal is a teacher, pays attention to everything you do, but Hiddink is more linked to the players. He gives more freedom than Van Gaal, but I worked with both of them pretty well.
The wrong team wanted me, by the way - of course United. I spoke with Van Gaal, and they even made an offer, but for me, it was not the right club and not the right moment.
When I was at Hamburg, 17 or 18, Ruud van Nistelrooy signed, and he helped me a lot. He saw my first training session, and he talked to me. He told me I was a good player. He gave me confidence, and I want to thank him for that.
Theater gave me the confidence to believe I could play something else, 'cause it was so difficult. It was me out of my comfort zone. It gave me the confidence to believe that I could push myself and challenge myself and still succeed. Yeah. I'm very, very glad I did it. And I'm very keen, now, to take what I learned there into more television and film.
I spoke with Van Gaal, and he said that I only had a one per cent chance of playing in my position, so I headed to Bayer.
Louis van Gaal trusted me; I played a lot of games.
When we talk my biggest influence, I have to say Van Gaal. He threw me in the deep end.
I'm grateful to Van Gaal: he brought me to United and I played 71 games so I wouldn't say a bad word.
My previous bosses - Louis van Gaal and Marcello Lippi, to name two - have all taught me something.
It is no secret that Louis van Gaal and I did not get along. But for me personally, the matter is closed and forgotten.
Gerard Houllier is a great coach. He made me grow. He gave me chances in big games, which raised my confidence. It opened my eyes to what I could do. It was through him that I managed to trust myself.
Without boxing, because of my neighborhoods, who knows what would have happened to me. It was always about following the leader. And I definitely was not a leader. Boxing gave me discipline; a sense of self. It made me more outspoken. It gave me more confidence.
