Stefano Palazzi, the man in charge of dealing with those involved in Scommessopoli, wants heavy sanctions to be imposed on the pair, along with Montreal Impact's Marco Di Vaio
The Juventus duo have been charged with sporting fraud as part of the match-fixing ring, with Palazzi wanting a three-and-a-half-year ban for the centre-back, and a year's suspension for the ex-Bologna winger.
The prosecutor is also demanding a year-long ban for Marco Di Vaio, the former Bologna striker who recently moved to Canadian side Montreal Impact.
Other prominent Italian footballers facing considerable penalties include Siena's Emilio Belmonte (four years), Giuseppe Vives (three-and-a-half years) and Daniele Portanova (one year), and former Bari trio Simone Bentivoglio, Stefano Guberti and Salvatore Masiello (up to three-and-a-half years).
The heaviest sanction, however, lies with Pierandrea Semeraro, as Palazzi is holding out for a five-year ban to be imposed on the ex-Lecce president.
The requests will now be reviewed by the Disciplinary Committee of the Italian Football Federation (FIGC).
