FIFA have been investigating Ecuador defender Castillo since April when they received an official complaint from the Chilean FA, who claimed that he was ineligible to represent Ecuador as he is a Colombian citizen who entered Ecuador as an illegal immigrant.
FIFA, who in June dismissed Chile's complaint with a ruling that Castillo was born in Ecuador have now been presented a stunning revelation in FIFA's inquiry into the case of Byron Castillo days before their Appeals Commission are due to rule on the matter on Thursday.
This new evidence could alter the identity of Qatar's opponents in the first game of the World Cup and who England will face in the last 16, as Ecuador face being kicked out of the World Cup after new evidence of a shocking admission from one of their players of using a false birth certificate, with the confession made in an official investigation that was covered up by the Ecuador Football Federation.
The controversy involving alleged fake identities and the alleged cover-up by the Ecuador Federation centres concerning whether Castillo, who made eight appearances in World Cup qualifying, was born in Ecuador or in Colombia.
The evidence contains an audio recording of an interview Castillo gave to investigators four years ago, in which he admitted that he was born in 1995 and not 1998 date in his Ecuadorian birth certificate with his names as Bayron Javier Castillo Segura, matching the details of his Colombian birth certificate, rather than the name on the Ecuador certificate, Byron David Castillo Segura.
Castillo is also heard narrating how he left the Colombian city of Tumaco for San Lorenzo in Ecuador to pursue of a football career.
In his narration he mentioned the name of the Ecuadorian businessman who provided him with a new identity.
The new evidence of a letter states that Castillo is a Colombian national who was born in Tumaco in 1995, as well as adding that they have audio proof of the player's confession.
Ecuador is billed to play the FIFA 2022 World cup host Qatar in the opening game of the World Cup on 20 November.
