The agent of Adrian Mutu believes Juventus must pay part of his client's £14.6m fine to Chelsea.
The Fiorentina striker was ordered to pay the fine after the Court of Arbitration for Sport upheld FIFA's ruling for breach of contract.
"I believe Mutu has to give back the money he earned at Chelsea," said Mutu's agent Giovanni Becali to calciomercato.com.
"But the rest should be paid by Juventus, Livorno and the Moggi family (Mutu's former agent Alessandro Moggi)."
Mutu was sacked by Chelsea in 2004 when he tested positive for cocaine, but the Blues complained when he joined Juventus following a drug ban.
The player's transfer to Juve turned out to be more complicated as Juve had no available room to buy another non-EU player from abroad and Mutu's move also involved fellow Serie A club Livorno, who signed the player and contemporaneously sold him to Juventus.
In the summer of 2006, Juve transferred Mutu to Fiorentina for 8million euros.
Becali has warned all parties involved in this complicated case that they are prepared to battle to get justice.
"We will put Juventus and those that are responsible for this situation in a difficult position," he said.
"We will get the best international lawyers.
"Today I will meet agent (Jean-Louis) Dupont (Jean-Marc Bosman's lawyer) in Florence and we will decide what needs to be done.
"Mutu is desperate.
"He has been abandoned by everyone, including those that made a fortune in his transfer to Juventus as a free agent.
"No-one at Juve has come out and said anything, nor the executives or his former team-mates.
"Mutu already paid a price with a seven-month ban and without pay.
"He is ready to give back what he earned.
"I will fight until death so that Mutu gets justice."Reuse content
