France, England and Germany never really called up a lot of players born outside their countries either. You can maybe make a case for France at one point, but only if you count players born in overseas French territories like french guyana, guadalupe, etc...otherwise, we're talking no more than 3-5 non-french born players...
These countries didn't really start calling up players until they were 2nd or 3rd generation or more. It makes sense too: the biggest difference between the big european and south american football superpowers and the rest of the world come down to population and infrastructure for the most part. So historically it'd be unlikely for these countries to call up players who weren't born there - italy in the 30s to 50s being the big outlier with naturalized argentinians of italian ancestry - since it's unlikely these players would be better than what they already had "locally". Immigration also took a while to really take root with immigrants being integrated into their football systems, which again, means guys like Vieira, Makelele would be outliers, since there's so many more french-born players compared to kids who moved there really young
Back to the african teams, have to say i'm somewhat surprised that ghana beat south korea, they're better than i thought honestly, while senegal looks worse than i expected. The others are pretty much performing to expectations. Morocco will make it through, pre-tournament i expected senegal to make it through as well, now i don't, and i think Morocco will be the only team to make it to the R16. Sorry
