Lucas Barrios: Paraguayo? Argentino?

South America is famous for exporting futbolistas to European teams, but what's less discussed is how many South Americans change nationalities for the chance to play in the World Cup. Here's a good article from Goal.com about the number of Argentina and Brasil-born players who play for other countries. Down here, the famous cases are of three "Argentine" players on the Paraguayan team who were born, to Paraguayan parents, in Argentina. It's a bit of a media cliché in Argentina that whenever Lucas Barrios (above) or one of the others score for the Paraguayan side, the Argentine press feels the need to mention that they are "really" Argentine. Paraguay's press took its revenge when Gonzalo Higuaín scored three goals for Argentina against South Korea--they mercilessly noted that he was born in France.
