I have watched Ghana, Cameroon,Nigeria, S.Africa, Ivory Coast,Algeria etc matches and each of these teams is referred to as 'The Africans', other teams from Europe or Asia and S. America are never referred to as 'The Europeans', 'The Asians' or 'The S.Americans'. Does it mean Africa is one big country like USA? Does Africa have provinces/states like here in Canada and USA? If so, why is Africa allowed so many teams and not just one team representative of the whole country?
