Gigi Del Neri would like to spark a 'mental revolution' at Juventus after Sunday's defeat to Lecce.
The Old Lady have been widely criticised, not least by Andrea Agnelli, for their inconsistency.
"We don't have explanations for the defeat to Lecce and we are all guilty," Del Neri said.
"But a week earlier the same team produced an aggressive style of football with Inter.
"The important thing is to have a different mentality starting from tomorrow."
As of yet, it remains unclear whether Del Neri will move Giorgio Chiellini back into the centre of the defence after the return of Armand Traore from injury.
