Because of an incident involving Super Eagles captain Ahmed Musa, FIFA has sanctioned Cristiano Ronaldo’s Saudi Arabian club, Al-Nassr.
The world football governing body has now barred the club from making any fresh signings for the upcoming Saudi Pro League.
Al-Nassr has failed to pay Leicester City the money owed to them as a result of Musa’s move.
Musa joined the Saudi Arabian Pro League club in 2018 for €16.50 million, shortly after shining at the World Cup in Russia.
The Knights of Naja have paid the transfer fee but have yet to pay the add-ons, despite a judgement by the Court of Arbitration for Sport (CAS).
Al-Nassr were ordered to pay the Foxes €460,000 in performance-related add-ons, according to Ben Jacobs.
However, the Saudi heavyweights have yet to comply with the CAS verdict, leading FIFA to prohibit them from registering fresh players ahead of the next season.
