Prosecutors have said that Conte was aware of match-fixing in a game which involved his Siena side and AlbinoLeffe and did not attempt to prevent the attempts to fix the match.
The 46-year-old was originally acquitted of the offence but prosecutors have appealed the verdict, meaning Conte could be questionned trialled again.
The former Juventus manager served a four-month touch-line ban in 2012 because of the case, but Chelsea's new boss has always denied any wrongdoing.
