Unbeaten Juventus were held to a 0-0 draw against Genoa on Sunday and, after the match, enforced a media blackout in protest at an offside decision which went against Simone Pepe.
After netting late in the second-half, Pepe was flagged offside and his side reacted angrily after the final whistle in banning their players and staff from speaking to the waiting media. "Footage speaks for itself," was the only comment on their official Twitter account.
Their fourth successive draw saw them fall four points behind AC Milan as the Serie A leaders won 2-0 over Lecce.
Juventus coach Antonio Conte had to watch from the stands after being sent off in Wednesday's 1-1 draw against Bologna, and he had also railed against the decisions of officials.
"We are never awarded penalties. The more we are denied penalties, the more annoyed we will be," he lashed out to Sky Sport Italia. "We may not get penalties, but at least it would not bad to get fouls outside the box, like the one that Marco Borriello suffered. After all, we have good free-kick takers."
