Former Juventus defender Claudio Gentile believes Andrea Pirlo's job is under threat.
Pirlo has struggled in his first season in charge at Juve.
“The facts are clear and sufficient. Juventus usually make a little revolution when there is a failure," World Cup Winner Gentile told Rai Radio 1.
“Surely, there is a disappointment. I don't want to blame Pirlo, but it's essential to have experience and know how to handle a group. Maybe he was not ready," Gentile added.
“Perhaps, it's early to say it's the end of the cycle for Juventus, but this has been one of the worst seasons.
“It's fair to make changes when a season is unsuccessful, thinking about who to replace and how."
