Zamparini said on Monday: “Guidolin has not changed his tactics in the last nine matches and we have lost seven times, earning one draw and a win with Livorno.
“I have told him that he is wrong, but he does not listen to me. He is causing a division in the locker room.
“If I were to sack him I would not hire another Coach, I would keep his assistant. In any case I will keep him – he put us in this difficult position and he must be the one to get us out.”
He added: “Things would have been different if we had only lost 2-0 last night. Roma gave us a football lesson and that is why I paid my compliments to chief executive Rosella Sensi.”
