holy crap that's what it is. I just looked it up and all of those countries match the character, so chile is red, argentina is blue/white striped, brazil is yellow, and Mexico has a green kit... Peru is white w/red stripe so it didnt work.... and West Ham is of course purple.
The fact that 3 of the 4 were in the copa final 4 might have nothing to do with it, but it's a heavy coincidence.
