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.

No matter how little we think anatomy should matter to one's social and political rights, surely we can't pretend biology doesn't matter in sports. Surely there's a reason we don't let adults play in the t-ball leagues, and a reason most women athletes want their own leagues.

First, you have to play good football so that you get to play for a good team. Then, hopefully, you achieve such a level that you are invited to play for your national side, in time for a World Cup if possible. Then, obviously, play a good World Cup. That's my dream.

The triathlon can be a very hard sport to train for. You see all the time when people try to improve - like their swim, for example: they train really hard for two to three weeks, and then when they go back to normal training, the swim goes back to where it was before.

If I go on to the pitch, do things well and the fans love me and my team-mates, too, we take on that energy which can change a game.
