Former Torino defender Massimo Brambati says John Elkann must accept responsibility for Juventus' problems.
Elkann is the CEO of Exor, Juve's parent company.
Brambati told TMW Radio: "To reset everything, you have to understand ownership. Does Elkann have clear ideas? Did he surround himself with the right people?
"For me, he's been putting in the wrong people for a long time in the wrong places. Paratici won 9 championships, then Cherubini and Arrivabene arrived, who couldn't sit there.
"Until yesterday, Calvo did marketing. How can he say that they'll take Giuntoli? Then this, who does he interface with? Why doesn't Calvo find a man of football?
"Today you have to put your hand in your wallet and change, even the coach."
