Juventus powerbroker Lapo Elkann has slammed their recent performances.
Elkann has warned he is unhappy with the players' form after defeats to Bari and Bayern Munich.
"My grandfather would have loved that Juventus had beaten Inter. He would not like to have seen the Juventus against Bayern Munich and even the Juventus we saw yesterday in Bari. Juventus have a great history and should live up to it properly," said Elkann.
"The last two games for a fan like me were horrific.
"The players are not giving credit to this history, they're not giving their best and this is not acceptable."
