Livorno are threatening legal action over Christian Rigano's move to Spain's Levante.
Last week, Livorno president Aldo Spinelli declared that Rigano was joining them from Messina, only for the veteran to sign with Levante this week.
"We have bought him from Messina," snapped a furious Spinelli. "We have all the documents and they are signed.
"It is true, we have not been able to reach an agreement on personal terms with the player, but I don't believe Messina can sell him to another club like that."
