Rome, October 26 - Napoli defender Paolo Cannavaro, the brother of Italy's retired 2006 World Cup-winning captain Fabio Cannavaro, was charged by Italian Soccer Federation (FIGC) prosecutors with an alleged match-fixing offence on Friday. Paolo Cannavaro, 31, is suspected of failing to report an agreement to fix the result of Napoli's match against Sampdoria in Genoa on May 16 2010. Sampdoria won the match 1-0 and qualified for the preliminaries of the Champions League. Backup Napoli goalkeeper Matteo Gianello was charged with the more serious offence of sporting fraud and several other people involved in football have been charged with involvement in fixing that match and a second-tier game between Portogruaro and Crotone in May 2011. Napoli have been charged with indirect responsibility for their players' actions. The club risks a penalty of up to six Serie A points and Cannavaro could face a ban of as much as six months if found guilty by an FIGC sporting tribunal. The move is the latest development stemming from a series of probes into betting-related match-fixing in Serie A. Over 40 people have been arrested since the Cremona-based 'Last Bet' criminal probe went public last year, leading sporting prosecutors to look at the case. They include Lazio midfielder Stefano Mauri and former Italy internationals Beppe Signori and Cristiano Doni. Juventus boss Antonio Conte is currently serving a four-month ban for failing report a deal to fix a match during his time at former club Siena. Former Bari defender Andrea Masiello, meanwhile, was this month given a suspended 22-month prison sentence after a plea bargain with prosecutors. Masiello, who had already been banned from soccer by a sporting tribunal, admitted to deliberately scoring an own goal to ensure Bari lost 2-0 to Lecce in the 2010-11 campaign, when they were relegated to Serie B. A Bari court found the 26-year-old guilty of criminal association and sporting fraud regarding the fixing of four matches. The new case has rocked the Italian soccer world again after Juventus were relegated and stripped of two Serie A titles for involvement in the Calciopoli match-fixing scandal in 2006. That scandal regarded schemes to have compliant referees officiate some teams' matches.
