My back to the goal, physically fighting off defenders, trying to bang my goals in, every week I have to do the business for this club. That's the life of a striker.

The real big stars only keep this up for about seven years.

When it comes to losing with United, I feel solely responsible for it. I can't help it. My brain will work like mad after a defeat. I want to know where I have made the wrong decisions, how I could have changed things for this fantastic club.

Messi is on a different level. The fact he is doing what he is year after year says that he is the best of all time.

The greatest player in the world. Ronaldinho? Absolutely. I just can't get enough of watching him play - he's a delight for the eye. His technique is incredible, his touch, his vision, he scores and he orchestrates everything. He's just the complete player. I know how difficult it is for a forward playing at this level, but for him it's so easy. He does it every single game and it's just unbelievable to watch.

Because people have read those things in the newspapers, they think it is true. Ten years ago all these things I have just mentioned would have upset me.
