"I believe Mutu has to give back the money he earned at Chelsea," said Mutu's agent Giovanni Becali to calciomercato.com.
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.
"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."
