I'm a very stubborn person. I think it has helped me over my career. I'm sure it has hindered me at times as well, but not too many times. I know that if I set my mind to do something, even if people are saying I can't do it, I will achieve it.

I hope I become a better player day after day. This is one of my goals. I want to improve in every situation, but when you are playing along with top figures, it is a quality bonus and a bigger effort. Besides, the Spanish Liga also gives you the chance to progress and improve.

Our performance during this World Cup has not been enough to progress further and both myself and all the players regret that and are hurt more than people realise.

Collectively with my design team we spent time working on the feel, fit and style to ensure the product is not only something I would wear but one which I would be proud to put my name to. I always want to challenge myself and this was such a rewarding experience for me. I'm very happy with the end result and I hope H&M's male customers will be as excited as I am.

You will go through tough times, it's about getting through them.

It's one thing I like about America - they respect the sportsman. They put them up on a pedestal. They don't try to knock them down. And that's a great thing, to be respected by the whole country. It's so patriotic!

Alex Ferguson is the best manager I've ever had at this level. Well, he's the only manager I've actually had at this level. But he's the best manager I've ever had.
