The Frenchman, who amassed 171 goals during a decade of service for the club, told stadiogol.it: "Defeat was not a term known and even a draw was unacceptable.”
Despite winning at the weekend against lowly Brescia, Juventus are suffering a horrid year. Scudetto aspirations evaporated long ago and even a place in the Europa League appears to be dependent on other results going their way.
Trezeguet, who now plays for La Liga battlers Hercules, said the Bianconeri's demise was down to the fact that they no longer possess the infamous Juve winning mentality.
"At Juve you were first or you were nothing," he said. "If we went out of the Champions League it was a tragedy. I saw team-mates who did not eat for a week."
Trezeguet stands as Juve’s all time leading foreign goal scorer and the decision to finally quit the Old Lady after 10 years was not his doing.
“They said 'we want young people, both Italians and foreigners', it will be a new adventure. They were speeches that after 10 years at Juve I could not even hear. I packed up and gave way to someone more suitable to what they wanted to coach.”When quizzed on his advice for the struggling club, Trezeguet suggested appointing Alessandro Del Piero president and making Pavel Nedved coach.
Trezeguet's reflections weren't all entirely negative. In particular he has fond memories of the fans.
"I will always be in love with Juve. [They] taught me how to win and made me a complete player. Juve are made to win."
