FIFA has already conducted an enquiry on this and has ruled that Byron Castillo is an Ecuadorian citizen. And as far as I know, whether he was born in Colombia or Ecuador should not matter, in case his Ecuadorian nationality is unchallenged. Naturalized citizens are allowed to participate in the FIFA world cup. I know that Chile football association is trying hard to get Ecuador disqualified. They should be ashamed of themselves. First they can't secure a qualification spot from the CONMEBOL. And now they are trying to get one of the qualified teams suspended.
The problem is not where the player was born and his neutralization in another country. And FIFA accepts neutralized players if he has never played in the A team of another national team. The question here is whether he deceived the authorities and in turn FIFA, this cannot be allowed.
Now, it's still shameful if this is some behind-the-scenes move by other countries. The information made public must be evaluated and a definite decision must be taken, so that this is not always the case.
In the first place, I believe it is unfair for a whole team or a nation to suffer punishment because of the fault of an individual. An individual has committed this shameful act, and he is the one who should be punished for it, not the entire nation as a whole. It is very unfortunate that FIFA is even considering the possibility of getting Ecuador banned from taking part in the World Cup. As far as I am concerned, it is really hurtful not only for the fans of Ecuador but also for the whole world. I just hope that Ecuador gets a chance to play in the World Cup and that only the player involved will be punished and not the entire nation as a whole.
