Leicester made a late move for Silva on transfer deadline day as the replacement for £35million Chelsea new boy Danny Drinkwater.

The Foxes requested a two-hour extension to get the deal over the line and were confident they submitted the required paperwork in time.

Leicester announced on Friday the deal was waiting on international clearance - but Portuguese outlet A Bola claim his Premier League registration was completed too late.

Silva, 28, will still become a Leicester player but he cannot be registered by the club until January at the earliest.
