My life has always been a series of challenges and I'm psychologically-prepared but this is the biggest challenge of my life.

I'm here to score a lot of goals. It's my specialty, that's what I've been brought here to do, and I want to score plenty ; like I did with Barcelona. And here, there's every reason to think I can do it.

I don't want my fans to have the same disappointment as me when I was refused by some players to sign my notebook when I was young.

Every time I went away I was deceiving my mum. I'd tell her I was going to school but I'd be out on the street playing football. I always had a ball on my feet.

I'm sure sex wouldn't be so rewarding as this World Cup. It's not that sex isn't good but the World Cup is every four years and sex is not.

I have ambitions I want to fulfil, to enjoy more success with Brazil.

We lost because we didn't win.
