He should be in the Spain squad if Brazil don't snap him up, he would be a good replacement for Michel Salgado
The current starting eleven RB is Sergio Ramos, that player is good with the ball in his feet but I don't like him that much defensively. Alves is better defensively than Ramos, and miles better than Salgado, who has past his best IMO.
Why isn't he in the squad then? probably stupid national pride. Pernia, an excellent LB has been nearly out of the WC, just because he was born in Argentina. Fortunately enough, Del Horno, the Shítski player has been injured and Pernia has been summoned.
Txiki Begiristain, the sport director of Barcelona (in Spain there are no managers, the coach coaches, and the sport director makes signings, don't ask me why, I preffer the english concept of manager) has said that they need somebody in the defence. I'd find very likely they try to sign up a RB, Alves in this case, as many of you could see Oleguer might be a good Catalan independentist, but definitely not good enough to play at Barcelona level.
It's not going to be easy.
