Switzerland: Italian clubs Juventus and Livorno have challenged FIFA's order to help Adrian Mutu pay more than 21.5 million euros ($29 million) compensation to Chelsea.
The Court of Arbitration for Sport says it registered separate appeals from Juventus and Livorno. No hearing dates have been set.
The Mutu case, sparked by Chelsea firing the Romania forward after his positive test for cocaine in 2004, will arrive at CAS for the fourth time.
In 2009, a CAS panel ordered Mutu to pay Chelsea more than 17 million euros (then $24 million) damages. The sum increased with interest.
This month, FIFA confirmed its dispute panel's further ruling making the Italian clubs jointly responsible.
Mutu joined Juventus as a free agent in 2005, though was placed with Livorno during his seven-month ban in England.
