Cagliari president Massimo Cellino says no decision has yet been made over the future of coach Massimo Ficcadenti.
Ficcadenti's job is in doubt after their defeat to Pescara on the weekend.
"The team and the players have not been in a position to give their best because of the Coach, because of me and because of the players themselves," he told GR Parlamento.
"It will take little for me to change the Coach, but I don't know whether all the problems can be attributed to Ficcadenti.
"To cut off Ficcadenti's head would be the simplest thing, but I wouldn't want to do that to a nice guy and a serious professional.
"I've not made any decision yet. And I haven't spoken to the Coach either, so I can't be sure who is responsible.
"Nevertheless, the season is still young."
