Juventus GM Beppe Marotta has raised Calciopoli in the wake of their defeat to Palermo.
During the defeat, Cesare Bovo clearly handled the ball in Palermo's penalty area after 34 minutes, but the referee Emidio Morganti waved play on.
"There is great bitterness among the lads," Marotta said.
"Before anything else, I would like to recognise the merits of the victors, but also the losers.
"I don't want to make excuses. Mine is a criticism towards the refereeing class in Italy.
"I wouldn't like to think that judgements made about Juventus regarding Calciopoli in away influence the refereeing.
"The so-called psychological subjection [suffered by referees] towards Juventus has now become arrogance.
"There have been sensational episodes which have damaged us recently. I can't understand why there is this attitude towards us."
