I really like Ronaldinho. He is the player I have watched the most and tried to copy the most, but I am still learning.

I have so many memories and have so many people to thank at Liverpool. I have to improve as a player. In my head, I always think this.

My confidence has been really building since my time at Espanyol.

I am the type of person who relishes the chance to stand up and perform under pressure. I have had to do that my whole career.

I think a great athlete transcends eras.

Someone asked me what part of the body is the most important to be strong - it's the big toe. The big toe especially, and the inner front-third of your feet, are what give you balance and will make you infinitely better at any sport, any physical activity and, as you get older, will keep you from falling.

When I came into the NFL, there were three things that were very important to me: money, power and prestige. I was powerful now because I was a famous athlete. I had prestige because I was doing what everybody wanted to do. And I had a lot of money.

Gradually, football has seen its appeal slip at the most basic levels. Pediatricians are advising parents not to let young children play organized football too early in life.
