Rome, February 1 - Diego Maradona has won a 40-million-euro dispute with the Italian tax authorities, lawyers representing the Argentine soccer great said on Friday. The Agenzia delle Entrate, the Italian inland revenue agency, said Maradona owed them the money for unpaid taxes on off-the-books earnings in sponsorship and merchandising deals from his time at Napoli. The wrangle has run for 30 years. One of the lawyers, Angelo Pisani, said a court had ruled that tax checks run on the time Maradona played for Italian club between 1984 and 1991 were invalid. "Now he can return to Italy a free man," Pisani said. Pisani added that the former player, who helped Napoli win two Serie A crowns and a UEFA Cup, would now sue the tax authorities for around 40 million euros in damages.
