Chiellini says even his own future is clouded following the arrival of new coach Gigi del Neri.
He said: "I don't know what the team will be. If the Coach follows his habits, it will be short and aggressive.
"As for the rest, everything has changed: it's a question mark. Many people with whom we worked in recent years will not be there.
"We need to make judgements in a year's time."
