A host of Italian news sources are reporting the allegation that current Juventus boss Antonio Conte was aware of match-fixing while at Siena.
The claim is being made by Filippo Carobbio, a midfielder who was part of the Siena side which Conte led to promotion last season.
Carobbio is one of numerous individuals who are being investigated by prosecutors as part of the betting match-fixing probe.
Details of Carobbio’s unproven allegations have been quoted in a variety of publications and websites in Italy on Friday.
The midfielder is suggesting that Conte knew of the attempt to fix two matches – the 2-2 draw between Novara and Siena and the Tuscan side’s 1-0 loss at Albinoleffe late last term.
These allegations are not new and come again on the eve of Sunday’s Coppa Italia Final between Juventus and Napoli.
Back in April, Conte denied wrongdoing and seemed unconcerned about Carobbio’s testimony.
“I don't have much to say. I've read that there’s an investigation, I'm very calm and I have faith in the institutions, who are just trying to do their jobs,” he stated at the time.
“No one has called me, but when and if they do, it will be my pleasure to see them and answer their questions.
“If anyone is looking to destabilise us, they'll find it hard to do. It will only make us more determined.”
Those collaborating in the betting scandal enquiry will have their 'evidence' taken into account should any potential punishments be handed out.
Anyone found guilty of attempting to fix matches or have knowledge of such could face a ban from the sport, possibly for life. Clubs may be docked points or even relegated.
Juventus do not risk any punishment as the investigation is based on games in last season’s Serie B campaign.
Conte may speak about the claims again in his pre-match Press conference on Saturday.
