FIFA has refused to accept Leicester’s documentation in support of registering new signing Adrien Silva, according to Sky sources.
The Foxes agreed a £22m deal for the twenty-eight year-old with Sporting Lisbon on Deadline Day, but had to request a two-hour extension to complete the necessary paperwork.
It is understood Leicester’s officials are working with the Portuguese club to try to correct the registration papers, so that the transfer may yet be sanctioned by FIFA.
It will be hugely frustrating for the club and midfielder who missed Portugal’s 5-1 World Cup qualifying win against the Faroe Islands on Deadline Day and remained in England hoping for a swift resolution.
Leicester targeted the 28-year-old as a replacement for Danny Drinkwater, who was sold to Chelsea for £35m in the final hours of the summer transfer window.
