In my youth-team days, I was always a left-winger who would stay close to the byline and put crosses in the box, so I could never cut inside and shoot. It was only when I joined Real Madrid and started playing in a more central position, and then on the right wing, that I suddenly realised I had a really dangerous weapon.

I never had problems with injuries as a kid or in the youth team. My injuries started at Chelsea, when I broke my foot during a pre-season game. That was just pure bad luck, but after that, I had some muscular injuries, too, so I had to get to know my body better.

You need to be very critical of yourself. There are a few very good managers who can make players better individually. Most managers think about the team process - and so you have to improve things on your own.

I guess my earliest football memories are of playing in the street and also the little pitches at school. I joined the local football team in my village when I was small, but we would play only once or twice a week. I honed my skills just by playing for fun with friends after school.

There was no professional basketball for me in the United States when I was in grade school and middle school. I could look to the Olympics and college basketball, but that was only on TV for the Final Four.

It's one thing to be 100 percent and go out and play football feeling great. It's another thing when you're not feeling good. You're sick, or you got a nagging injury, and you gotta go out in the cold and go across the middle where a guy's coming full speed at you trying to kill you.

My father is a Marine. My brother is a Marine. I almost became a Marine. I'm no stranger to fight training. I used to do jujitsu and boxing as a kid. I was a running back in football for my high school and my college. I played ice hockey as well as did theater. So, there's always been a physical nature to me.

I used to play football with a load of lads, and I would be like a secret agent going out with a hat on so they wouldn't see my hair in a bun.
