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.

For an individual, playback singing is not enough to sustain a career, and it is not really a main source of income.

The tech company needs to win in the war for talent. This means much greater focus on the employee, not simply as cog in the machine, but vital member of a programming team in a race against time and competitors. Wall Street is up-or-out, dog-eat-dog, survival of the fittest.

I didn't think acting would be a lucrative career.

The more I go on in this career of making albums, writing songs and playing music, the more I think of each album as a movie. I really wanted to make a film, but making a film is much more expensive than making a record.
