This story is total garbage as according to census surveys Argentina has 2 percent of the population as of Afro-Argentine ancestry and many are Mulatto to Quadroon types. So this idiot writer wants roughly half the team of Argentina to be Mestizo or Mulatto and for them to lose like a city state Latin American country at the World Cup?
The only sport I have seen Afro-Argentine athletes in is boxing and even there it's a rare occurrence. Here is one boxer who had a supporting role in Rocky....
PS the Argentine team has lost German-Argentine players as when I was younger I remember seeing German surnames on their national roster and it's been decades since I have seen them. This idiot writer would never talk about the dearth of these athletes on the national team.
