Juventus director general Beppe Marotta was furious with the referee and demanded “respect for our team.”
The Bianconeri were held 0-0 by Siena  this afternoon, but had strong penalty appeals for a Simone Vergassola handling offence.
“I don’t want to be discussing this through the media, but seeing as clubs are not allowed to communicate with the refereeing designators, this is how it must be done,” said Marotta.
“At times it is only right to make our voices heard so we can defend the club’s rights. Juventus deserve respect and today it would not be fair to speak only about the players.
“Everyone could see we were denied a clear-cut penalty, but unfortunately this habit has been dragging on for a while. We’ve only received one spot-kick all season.
“All we are asking for is respect for our team. It is natural that the Serie A leaders should be assigned a referee of international experience.
“Juve do not like to recriminate, but in some cases it becomes inevitable, especially when you are not allowed to put away potentially decisive points in a campaign.”
