You mean English ?
Yup. I wrote English and not Brit cos it's football, and he played for England under 21. Tripple nationality it seems. British/Nigerian/American. Born in US cos his mum went there at 7 months pregnant and the airline refused to fly her back. Born there and returned to Britain 2 weeks later. FIFA rules say can switch allegiance when they turn senior. All totally above board. But now he can't switch cos he is set as American per FIFA rules.
Same sort of scenario as Boris. He was US citizen till 2017 or so. And Boris is crap at football so far as I am aware.
I remember the rules from years ago, so could be wrong. Because the PRC has "naturalised" players on it's team. Who played international at under 21 for other nations. And there was a bit of a kerfuffle when they started playing for China. Especially given that China does not allow other nationalities to become citizens. And then during qualification for this WC there was another kerfuffle cos China accused another country of using naturalised players.
I also remember at the time there is another FIFA rule about State Government influence on the sport. FIFA lets China away with that but punish other Asian nations.
And FIFA and the US just broke that rule too with the red card thing.
I don't know why FIFA bothers with rules really.
