As far as I know, the naming customs in all Spanish and Portuguese speaking countries are consistent. It's just cumbersome to use your entire name so they simplify it by just using the paternal name.
I wouldn't be surprised if there were players around who used the maternal name instead, but you've also got people like Cristiano Ronaldo dos Santos Aveiro who don't use any of their surnames.
Back on topic: big love to Uncle Emery, giving Villa it's mojo back.
