racial quotas are a very stupid thing...
if anything federations should clamp down on players changing nationality. happened in Portugal with Deco, Pepe and Liedson. the first two i can understand, Deco came to Portugal at age 20 and Pepe in his teens, the latter especially said from the start that he wanted to play for Portugal. he even lost his Brazilian accent lol.
Liedson changed nationalities in his thirties or at least late twenties and never seemed to care much about it.
new national coach Paulo Bento has stated that under his watch no naturalized players would be joining the national team.
