The Italian football federation (FIGC) found Conte guilty of failing to report attempts to influence the outcome of two Serie B matches against Novara and AlbinoLeffe in the 2010-11 season when he was in charge of Siena.

The 43-year-old had previously reached a plea bargain deal with prosecutor Stefano Palazzi over a three-month ban, but the agreement was rejected by the disciplinary committee.

Conte has now been slapped with a suspension until the end of the 2012-13 campaign instead.

Furthermore, Angelo Alessio, Conte's assistant at both Siena and Juventus, has been handed an eight-month ban for his involvement in the match-fixing probe.

Lecce and Grosseto have both been relegated from Serie B, while the presidents of both clubs have been suspended from all football activities for five years.

Meanwhile, Juventus duo Leonardo Bonucci and Simone Pepe are among the players who were acquitted due to a lack of evidence, with veteran striker Marco Di Vaio walking away unscathed as well.

A statement from the FIGC read: "(These are) the judgments issued today by the National Disciplinary Committee, chaired by Sergio Artico,in relation to two cases of match-fixing.

"Among the officials, the more severe penalties are those of the president of Grosseto, Camilli, and the former president of Lecce, Semeraro, (for both a five-year ban); the disqualification of 10 months for Antonio Conte, currently coach of Juventus, and for eight months his deputy Angelo Alessio."

Juventus later released a statement in support of Conte and Alessio.

"Following the verdicts given by the FIGC's disciplinary committee regarding the involvement of Juventus employees in incidents while at other clubs, Juventus are extremely satisfied with the acquittal of footballers Leonardo Bonucci and Simone Pepe," the statement read.

"Furthermore, the club underlines its full support for Antonio Conte and Angelo Alessio, in the hope that their innocence will emerge during the appeals process.  

"The coaches' legal team, comprising of professionals chosen by the parties themselves in complete agreement with the club, is already drawing up the grounds for appeal, in the firm belief that the coaches had no involvement in the matter.

"Antonio Conte and Angelo Alessio will be assisted by lawyers Antonio De Rensis and Luigi Chiappero, and additionally by Giulia Bongiorno."

The verdicts come only one day before Juventus' Italian Super Cup match against Napoli on Saturday.
