Conte has already served a ban imposed by the Italian soccer federation in connection with the 2011 case.
Prosecutor Roberto di Martino has cited a match against Albino Leffe, claiming Conte knew of match-fixing efforts. He requested the sentence and 8,000 euro fine in a closed-doors hearing in Cremona on Tuesday.
Conte’s lawyer, Leonardo Cammarata, said the defence is due to make its final statement to the court on 11 April and a verdict is due in mid-May.
A Chelsea spokesman said the club would not comment on an ongoing investigation.
