Fav. sports: soccer and tennis
Here's why: soccer is like the most internationally recognised sport. Nearly everyone knows how to play it, after all breaking it down to fundamentals, it's just kicking a ball around. It's casual yet involves so much skill and technique in high level play. Thus, there is a great balance in soccer. Tennis is similar except without so much focus on teamwork and formation (no passing).
Fav. teams: Chelsea F.C. and F.C. Barcelona, Argentina's national soccer team
Here's why: Chelsea wasn't quite a great team until they were bought by the Russians back in 2001. That's probably why they could then afford managers like Jose Mourinho etc and players like Torres. Barcelona, on the other hand, is purely the best team out there. Their forwards are legendary.
Fav. players: Drogba, Torres, Lampard, Messi, David Villa, Xavi, Federer (cos he has all the finesse)
I could go on about the teams and players I don't like but I'll probably offend a lot of people. Here's the main example: Cristiano Ronaldo (ballhog).
