Cagliari's players admit they've been put through the wringer by new coach Nedo Sonetti during international week.
"He is in great form. We all know him, the Coach is a determined person with a very strong character."
There are also big tactical changes that come with the replacement on the bench, revealed Ferri.
"Giampaolo asked the wide players to push forward a lot, but with Sonetti we will be more anchored to the back and still support the strikers.
"The way we achieve that is moving the whole centre of the squad higher up the field so we won't let our opponents hit us on the counter.
"I am sorry for Giampaolo, he just paid the price for the fact the results did not come."
