In 2006 I was asked to sing at the World Cup in Germany, and in 2010 I was fortunate enough to be asked again.
The important thing for me was that the World Cup should travel round the world.
It wasn't until 1999 when my idols Mia Hamm and Kristine Lilly took home the women's World Cup trophy at the Rose Bowl in front of 40 million TV viewers that I remember thinking how rare it was to see women play sports on TV.
The truth is that I don't have a favourite goal. I remember important goals more than I do favourite goals, like goals in the Champions League where I had the opportunity to have scored in both finals I have played in. Finals in the World Cup or Copa del Rey are the ones that have stayed with me for longer or that I remember more.
I was lucky enough that my parents knew about World Cup skiing, so since I was really little, we were watching World Cup winning runs.
I'm aware that the World Cup is probably the greatest spectacle in the world of sport, and that's despite the referees that have been found to have fixed games specifically.
I feel that World Cup cricket should be played like football in which all the 160 countries take part. If only a handful of countries are going to keep on playing in the World Cup without making the game popular, I will be a sad man.
I would trade all the individual awards I've won for a World Cup.
The World Cup focus is football. Team U.S.A. is more than football.
The World Cup is a very complicated tournament - six games, seven if you make it to the final - and maybe if you lose one game you're out, even if you're the best.
Doing jersey advertising for the World Cup is not in the same universe as putting advertising on NHL sweaters.
Some anthems are great for sports. You've got the Russian national anthem... 'O Canada,' how wonderful is that for hockey... but I chose the Italian national song because at my first World Cup, I saw the Italians play four times, and they won all four times - they won the championship.
The World Cup must remain the number one competition, because it is our only source of money and, with that money, we can develop football in the whole world.
