Look I heard the commentary about where some of the players came from so I lost interest.
Players will come from various ethnic backgrounds (as a Scotsman, 99% of my country’s team are white and Celtic/Anglo-Saxon, but one player is of black African and white Scottish parentage, ironically he is probably the most gifted player), but the World Cup is for international players. Just as a foreign NHL or NBA player cant play for America at the Olympics.
You cannot buy players to play in the world cup, they have to be of the nationality of the nation they are playing for. Either born there, of that country’s parents, or by naturalisation.
