In my years at United, I witnessed some signings who, over their careers, transformed the fortunes of the team. From Eric Cantona, when I was an apprentice, to Dwight Yorke, Ruud van Nistelrooy, and Wayne Rooney. These were great footballers who became great United players.
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.
It is a great privilege for me to play at Man United, where great players like Dwight Yorke and Andy Cole have played.
I saw United matches on TV as a kid in Sao Paulo. I loved watching Ruud van Nistelrooy. He was a hero for me because of the way he scored goals in all competitions.
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.
When I started supporting Man United, Dwight Yorke and Andy Cole were my heroes growing up.
I liked watching Dwight Yorke when he was at Man United. I'm a Man United fan.
Manchester United isn't about Wayne Rooney. Manchester United is about the team, the club.
Robin van Persie and Wayne Rooney are both outstanding players.
As a private person I think I am now totally different from Ruud van Nistelrooy the footballer.
It's special - when you start playing, you are aware of names like Wayne Rooney and Robin van Persie; you have seen them playing and know what great players they are. So it's fantastic to have a chance to line up with them. I'm really pleased with how that understanding has started off.
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.
For 99.9% of the players there, they are at United because they want to be at United, and it is their dream move. That gives United a little bit of an advantage over other clubs, where some players are maybe there because there was financial pressure for them to be sold.
I think about the great players with whom I have shared a pitch: Eric Cantona, Zinedine Zidane, Pirlo, Xavi, Cristiano Ronaldo - and the greatest of them all is Messi.
What do you think of Manchester Uniteds three Rs - Rooney, Ronaldo and van Nistelrooy?
There were great players at United, and I just didn't have the chance to play, which was fair. It was difficult getting into the team, that's all.
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.
