Catania general manager Pietro Lo Monaco has attacked AC Milan chief exec Marco Fassone.
Lo Monaco was reacting to claims Milan coach Vincenzo Montella could soon be sacked.
"Fassone knows nothing about football, so he is creating chaos and making it very difficult for a very talented Coach like Montella," insisted Lo Monaco.
“In the derby, the team that risks the most going in is certainly Milan, perhaps with a change of management on the horizon.
“Inter, on the other hand, are on a fairly linear path, with some ups and downs."
