Genoa president Enrico Preziosi has blasted Parma pair Christian Panucci and Tommaso Ghirardi.
During Sunday's 2-2 draw, Preziosi came face to face with Ghirardi and only the intervention of security avoided a scuffle.
"He knows exactly why I am angry with him," said the Rossoblu patron. "Ghirardi cheated us on the transfer market and I am not going to speak to him again.
"I don't understand why he wanted to greet me in front of the Press. He knows what I think about him
"It's a personal affair which will only be solved if he says sorry."
Preziosi also had trouble with former Genoa man Panucci.
"Panucci is a hot head. Three months ago he attacked one of our directors. There is something wrong in his mind, he is always very nervous. He complained because we didn't call him when we were negotiating his transfer.
"I shouldn't have pushed him but I dare anyone to come to my home and start offending me."
