Can you tell me what advantage there is for a European player to go and play for a country like that and be naturalized in Indonesia? I think that if there was the possibility, everyone would do the opposite. I don't think they would want to have only Indonesian citizenship. I think that playing in Europe is already a great privilege for a few, so they would do well to stay where they are.
Actually, this goes back to the quality of the players because if they stay in Europe or meaning waiting for a call from the national team in their respective countries with the quality and competitiveness to enter there then they do not have the opportunity or even if they are called they will probably only fill the bench that's why they choose to be naturalized because there is an opportunity to be a starting line up and play against other countries such as the case done by Indonesia because it can be said that most of the naturalized players do not have the opportunity to play in the main national team.
One reason may be that they feel they have no chance of making it into their home country's national team. However, I am quite sure that naturalized players are also offered attractive deals that make them interested in joining, whether financially or in other ways. Another reason I think makes the most sense is that naturalized players essentially have dual citizenship. Therefore, they may choose to become naturalized players out of love for the country they ultimately choose.
And many people don't know about Indonesia. When soccer players become famous here, they automatically become like famous artists with incomes that may even exceed their soccer earnings. Even one of the foreign coaches who trains the Indonesian national team has experienced this advantage. Becoming popular in this country can really be a lucrative source of income.
As a European, I have never heard of an Indonesian footballer who is strong enough to play in important competitions like the European ones, and there are many even in the lower leagues. Here, football is something else, it is always played everywhere and there are strong players in every corner. They shouldn't naturalise people at random, but rather take them from their country of origin, and it will be a better world.
