Juventus GM Beppe Marotta refused to snap back at Palermo president Maurizio Zamparini ahead of Sunday's victory.
Zamparini has accused Juve of "ruining" Paulo Dybala since his summer switch.
Marotta replied: "Zamparini is the kind of character you find in folklore, he's an explosive figure.
"The best response to that is silence, albeit with respect for him as a friend."
