Genoa President Enrico Preziosi has threatened to sell the club if he hears one more insult aimed at his family.
The 62-year-old met with supporters yesterday to express his unhappiness at their recent behaviour.
"Thanks for your criticism because it helps me grow," Preziosi said.
"If I ought to hear you repeat them one more time, even through the voice of just one person, in an episode like last Sunday's I guarantee you that I will keep the club safe, but this will be my last year here.
"In June, I would put the club up for sale and we would no longer be here in Genoa. I don't want my kids to be insulted. We don't deserve insults from a stupid minority who shouldn't even be in the ground.
"Come and see me and I will refund your season ticket."
