Inter general manager Ernesto Paolillo also warns Rafa Benitez that “there needs to be a change of attitude,” as Fabio Capello joins the list of potential replacements.
President Massimo Moratti blasted the Coach and his side for their humiliating 3-0 defeat to Werder Bremen and demanded a new approach.
“I agree with the President that there needs to be a change of attitude and hope everyone takes that on board,” declared general manager Paolillo.
“The Club World Cup is an extremely important tournament and we must give it our all to bring home the trophy.”
It has been widely reported that Benitez will be sacked if he does not win the competition in Abu Dhabi this month.
However, there are even suggestions that Rafa's time is up after the Club World Cup regardless of the result.
Former Nerazzurri goalkeeper Walter Zenga is ready to take over as caretaker manager in January.
Other reports claim that England manager Capello is among the potential replacements, battling it out with Barcelona's Pep Guardiola for the permanent position in June.
Capello had already been linked to Inter several times in his career, but never made that step.
In the summer the England chief had been the hot favourite to replace Jose Mourinho before extending his contract with the FA.
