The former striker pointed to the Bianconeri’s squad quality as the real issue, warning that sacking Tudor would be a huge mistake.
Juventus extended their winless streak to seven games, but still showed glimpses of promise at the Bernabeu, challenging Madrid for long periods before Jude Bellingham’s close-range strike decided the match.
Speaking to Viva el Futbol, Cassano praised Tudor’s tactical organisation and mentality, asserting that the 46-year-old is doing his best with limited resources at his disposal.
“Igor Tudor is great: a great person, a great coach, a great communicator, he has a great personality, and I'm on his side,” Cassano said.
“At the Bernabeu, he showed that he played a great match, in a world-class stadium. He could have scored a couple of goals, he could have conceded, he played the game brilliantly. But then, guys... what kind of players does Juve play with?”
