Former Inter Milan chief Ernesto Paolillo says it's crucial they qualify for next season's Champions League.
Next year only three Serie A representatives will enter Europe's top competition.
"When UEFA's new financial fair play regulations come in, we will all sooner or later have to knock down our expenses," Paolillo told Tuttosport.
"Qualifying for the Champions League is fundamental, as without third place we'd have to further reduce our budget.
"I'd give the team 6.5 out of 10 for this season. It wasn't a great start, but we did well to get back on our feet.""Do not expect any big January buys, as we will only do what is necessary to fill the gaps. There is less money around and the rules wanted by Michel Platini force a more careful gestation of resources.
