Internazionale are set to be investigated after allegations of spying on referee Massimo De Santis in 2002.
The Italian Federation (FIGC) are set to open an inquiry into the claims made by the official, who is currently serving a four-year ban for his involvement in the match-fixing scandal which broke this summer.
Outside the footballing world the manager of Italy's Telecom company Marco Tronchetti Provera quit in the wake of a phone tapping scandal, but remains a member of the Stadio Giuseppe Meazza's management.
De Santis has accused the club and in particular supremo Massimo Moratti of hiring a private investigator to tap his phone, along with his wife's and former Nerazzurri frontman Christian Vieri, while Moratti wholeheartedly rejects the charges.
"It's absolutely groundless. Inter aren't involved," Moratti insisted.
"I think they are really serious because you can't ignore the damage he is causing by making these statements."
Inter would be in line for a fine though if found to be in breach of the first article of the sport's code of justice.
