which countries' greatest athlete or athletes are footballers?

Argentina: I don't think Juan Manuel Fangio had as much as of an impact than Messi or Maradona. Or Senna has in Brazil.
Hungary
France
Liberia
Portugal


Probably, but i have to consider these atlethes.
Germany: Schumacher, Graf.
Brazil: Senna
Italy: Valentino Rossi.

Cameroon: Joel Embiid is at least the best 5 basketball players in the world. Etoo might be in the top 5 in some years. However, basketball does not have the same appeal as football.
