Cagliari fans are furious with the sacking of coach Roberto Donadoni.
Massimo Ficcadenti is expected to sign for the Sardinians over the weekend, but in the meantime Cagliari ultras are planning a protest.
"We won't tolerate being taken for a ride anymore," slammed the message on a Facebook page launched by fans on Friday.
They accuse President Massimo Cellino of axing Donadoni in response to the recent row with David Suazo.
The Honduras striker trained with Cagliari for a week, but was told to leave over a contract dispute. He has now signed for Catania.
"After a failed transfer market strategy, Donadoni pays the price for having defended Suazo.
"Now Larrivey is first choice in attack, so another season of disappointment awaits us. Meanwhile, the stadium renovations are up in the air."
