Juventus coach Antonio Conte will be questioned over his alleged role in the Italian match-fixing scandal on July 13.

Conte, who coached Juventus to the Serie A title last season, is under investigation for alleged wrongdoing while in charge of Siena in 2010-2011.

The Italian football federation prosecutors will question Conte either in Rome or Chatillon, where Juventus will hold its preseason training camp.

The finger was pointed at Conte during the testimony of Filippo Carobbio, who played under Conte at Siena. Carobbio will be questioned again three days earlier.

Siena president Massimo Mezzaroma's hearing will take place on the same day as Conte's.

Napoli goalkeeper Morgan De Sanctis was scheduled to be questioned on Thursday, but his hearing was brought back to Tuesday as the Italian shotstopper was already in Rome after returning with the rest of the Italy squad from Euro 2012 the day before.

Napoli coach Walter Mazzarri will be questioned on Friday, while Juventus striker Fabio Quagliarella's hearing takes place on July 9.

Around 50 people have been arrested since last year in the investigation into the latest match-fixing scandal to hit Italy. Zenit St. Petersburg defender Domenico Criscito was dropped from Italy's Euro 2012 squad after being questioned at the national team's training headquarters shortly before the tournament.

The investigation was started by judicial authorities in Cremona last year. It has resulted in former Atalanta captain Cristiano Doni being banned from football for 5 1/2 years, and the arrest of former Lazio captain Giuseppe Signori as well as current captain Stefano Mauri.

Prosecutors in Cremona, Bari and Naples have detailed an extensive match-fixing ring stretching as far as Singapore and South America that was allegedly in operation for more than 10 years.

Italy has only recently recovered from the 2006 match-fixing scandal — known as Calciopoli — that resulted in Juventus being relegated to Serie B for a season, plus points penalties for several other Serie A teams and long bans for club and refereeing officials.
