Some people like Messi didn't have to learn a lot as his is a natural style. But of course you can improve your technique, your football intelligence, your everything.

I still feel it was a privilege to be a part of this team the past years, that I helped make Barca the best team in the world.

It is my goal to stay with Barcelona for a long time and be successful here.

The footballer's career is very long and staying on the top for many years is always very difficult.

I've tried very hard to stay grounded with my family, my ol' buddies, nature, music, and creativity.

I was born William. My father was William. I came from a big family, I hated being called Billy. Willem's a nickname; it's a Dutch name, very common in the Netherlands.

I'm enormously proud that I can do a deal with the National Women's Soccer League to showcase the power and passion of women athletes as positive role models, not only for my daughter but also for my son.

I owe a lot to my family; we're a strong unit.
