I hope you're asking about their skills on the field--when I watch football, I don't spend a ton of time checking out the players for their looks.
That being said--man, Brazil can really churn out players, huh?
I started watching a fair amount of football when I moved to London, especially during the Olympics. I have to admit, Neymar pulled his own weight during the Games--that match against Belarus was tight, and he owned that brutal shot. I haven't seen as much of Alves, but I'm looking forward to seeing both of them play FIFA 2014 on their home turf in Brazil!
