The reason why they opt for European teams is because the fanbase is 10x bigger, facilities and coaching staff are much better, and they get huge endorsement deals in those countries. It's the hard reality, but aside from them being away from their true roots, it's more pragmatic for them to be on those EU rosters.In order for those players to play for their motherland countries, their respective countries need to step it up when it comes to investing in great facilities and conching staff, also doing a proper job of recruiting. All those African players in EU national teams were recruited by scouts, so African teams need to hire good recruiters also to convince them to join.Plus, those teams will almost always qualify for the World Cup, whereas some African teams can go decades without qualifying
It's bigger than football players. The Congolese youth in the West does not have pride in their origin. I blame their parents. Congolese parents do not teach a sense of pride to their kids.
