Leicester City's bid to officially complete the £22m signing of Adrien Silva before January is hanging in the balance after they missed the deadline to register him by just 14 seconds.
Fifa have refused to accept Silva's registration after his move from Sporting Lisbon, five days after the deal and terms were agreed late on deadline-day.
And it has emerged that is because Leicester failed to register the player by a matter of seconds, meaning Silva is unlikely to be able to play for the club until the New Year.
Leicester insist they are still attempting to resolve the issue and are in dialogue with Sporting and Fifa, in a bid to push through the transfer.
Leicester moved for Silva after agreeing to sell Danny Drinkwater to Chelsea for £35m but asked for a two-hour extension from the Football Association to finalise the paperwork.
