Former Juventus Jose Altafini believes the players have lost their hunger under coach Andrea Pirlo.
Juve and Napoli meet on Wednesday night with fourth place up for grabs.
Altafini told Calciomercato: “Wednesday's challenge, the recovery of the match not played at the beginning of the season, it is giving away only one place in the Champions League.
“I think that Juve, after nine league titles in a row, have lost the 'hunger' they had, after all it is also normal, and then, even if they have an ace like De Ligt, his defence is no longer the same."
