When I played for Stuttgart, I met Manchester United and Chelsea. With United, I immediately think of the duels with Ryan Giggs and Paul Scholes and with Chelsea, it was John Terry. Those players are symbols of their clubs and the success they had at that time.
If I had a Paul Scholes in my team, everything would be around him. At Manchester United, they saw it like that, but I think Paul Scholes is one of the best I've played against in this league, and seen anywhere.
What United have got that Chelsea haven't is Paul Scholes. I think he is different to anything else in English football.
During my time playing for England we had Wayne Rooney, David Beckham, Michael Owen, Steven Gerrard, Frank Lampard, Paul Scholes. They were world-class players playing for Chelsea, Man United, Liverpool, Arsenal, all legends of the game.
I liked the generation of Paul Scholes and Ryan Giggs, who I admired. I was a little bit jealous of Karel Poborsky who played in Manchester and experienced great matches. I know he still feels that love.
When I was a kid and my dad was playing for Man United, I used to stand behind the goal watching Eric Cantona, David Beckham, Paul Scholes, Mark Hughes, Andrei Kanchelskis, Ryan Giggs... and I used to try to save all their shots that went wide, imagining I was deciding the title for United.
Scholes was playing tiki-taka football when nobody in England knew what it was. He was another of those players, like Denis Law or Bobby Moore, who at 15 probably looked as if he wouldn't make it. Too small, you would think - can't run, dumpy little ginger nut - but then the ball would come to him and he would dazzle you. He was the best footballer in that Manchester United midfield, better than Ryan Giggs and Roy Keane.
Many great teams have players who have come through the youth system or have been at the club for a long time as their captains. I'm thinking of Steven Gerrard at Liverpool, John Terry at Chelsea, Raul at Real Madrid, as well as Puyol at Barcelona and Gary Neville at Man United.
I have played with some great players during my time at United but I would have to put Paul Scholes down as the best.
The biggest clubs in Europe, whether they be Barcelona, Madrid, Manchester United, or Chelsea, always want to win, whatever they are participating in.
I learned so much during my time at United. Sharing a dressing room with Paul Scholes, Cristiano Ronaldo, Wayne Rooney, Ruud van Nistelrooy, and Ryan Giggs at such a young age was an amazing experience. I didn't play as much as I would have liked, but it was a master's degree in development both as a player and a person.
I had offers from other English clubs - Manchester United, City and Chelsea, who were the club that more rapidly resolved my transfer and the one that showed more interest in me.
Rooney is one of the best players in the world and I love watching him play. But if you had to pick out only one, then for their history and for all that they have achieved it would have to be Paul Scholes or Ryan Giggs. They are two shining examples for any player.
I really rate Paul Scholes, because he hasn't got the high profile of many of the Manchester United players, he doesn't get too much attention, but he is one very good player. He is an intelligent player, he works hard and he scores some great goals. He is not flamboyant and is a quiet lad off the pitch but he is a tremendous asset to Manchester United and to England. He has already got my vote as player of the year.
I admire Arsenal and the philosophy that the young players have. Liverpool, with their Spanish players, they also have an incredible squad. And Manchester United and Chelsea are teams that are very big, like Real Madrid and Barcelona, with money and incredible players.
During the Sir Alex Ferguson years, you would see all those great players - Roy Keane, Paul Scholes, David Beckham, Ryan Giggs, Jaap Stam, Ruud van Nistelrooy and Cristiano Ronaldo, to name just a few - and you'd quickly realise why Old Trafford had an aura like nowhere else.
As I said, when I played at Chelsea I give always my best to help the team but now Manchester United is my club and I will try to win there.
