Napoli president Aurelio de Laurentiis has enjoyed a swipe at Inter Milan counterpart Steven Zhang.
De Laurentiis has questioned Zhang's commitment to the Nerazzurri.
The movie mogul said at an awards gala last night: "Every now and then I see him getting interested, even if when he shows up at the stadium he usually loses.
"Then when we see him he has the face of a beaten dog."
Napoli sit top of the table, 15 points ahead of second-place Inter.
