FIFA President Gianni Infantino has denied wrongdoing after leaked documents suggested he signed off on a contract with two businessmen who have since been accused of bribery.
Hugo and Mariano Jinkis bought TV rights for Uefa Champions League football and immediately sold them on for almost three times the price.
The 2006 contract was signed off by Infantino when he was a Uefa director.
Infantino says he is “dismayed” that his “integrity is being doubted”.
News of the contract came to light after 11 million documents were leaked from the Panamanian law firm Mossack Fonseca.
Uefa initially denied doing business with any of the 14 people who have been indicted by the FBI in its investigation into corruption in world football.
It has now told the BBC the TV rights were sold to the highest bidder in an open and competitive tender process.
A senior Fifa source has told the BBC the deal should be examined by the governing body’s ethics committee in the interests of transparency.
