The trend is like that, because to play at the European level they need to compete fiercely with other players and the exposure they get may be less, whereas when they choose to represent their ancestral nations, it can give them a better position and it can also directly help the country they defend to improve the quality of play and give them the opportunity to serve their country. Especially now that African countries such as Senegal, Morocco, Algeria, Nigeria, and several other countries are trying to improve the quality of their national teams.. the presence of players of African descent might be able to reshape African national teams and make them even more qualified.
Indeed, choosing a country of descent can give a player the opportunity to help their chosen country compete in the World Cup. This also helps maximize their potential. However, this can also be a mistake, such as several naturalized Indonesian national team players who lack playing time in the main squad. They have sacrificed their citizenship for Indonesia, but cannot make the starting eleven. How do these players feel? There will be disappointment for sure. This means it's not just about trends, but also the player's readiness to choose their country as their new citizenship; they must accept the risks too.
There is no country that does not like a good footballer especially, when he has great potentials in him. If the players that nationalized in Indonesia, because they want to be part of Indonesia national team is not worth to be included in the first eleven of the team, they will not be included. On the one hand, if they are professionals and are among the best first eleven, these players will definitely, be included to the team first squad.
