FIFA has penalised Al-Nassr, a Saudi Arabian team because of a dispute involving Ahmed Musa, the captain of the Super Eagles.
According to the world football regulatory body, the squad is no longer permitted to add any new players until the start of the new Saudi Pro League.
Al-Nassr owes Leicester City money for the acquisition of Musa, although they have not yet received it.
In 2018, Ahmed Musa signed a €16.50 million contract with the Saudi Arabian Pro League squad shortly after making a mark at the World Cup in Russia.
The Knights of Naja had already paid the transfer fee but not the add-ons despite the Court of Arbitration for Sport’s (CAS) ruling.
However, the Saudi Arabian giants are yet to obey CAS’ ruling, forcing FIFA to ban them from registering new players ahead of the new season.
Al-Nassr were mandated to pay the Foxes €460,000 in performance-related add-ons, according to Ben Jacobs.
