I think the country that can actually replicate this and be even better is Nigeria.
The untapped potential that country has when it comes to football is absolutely crazy.
A football mad country with a population of 200 million plus people. Build them stadiums, invest in these leagues and youngsters and all these talented players with dual nationalises will be jumping at the chance to represent the country of their origin.
The money that will be pumped into the country by doing this would also be mad.
