Former Juventus president Giovanni Cobolli Gigli has slammed the performance of the current regime.
Juve won't be in Europe at all this season after finishing in seventh place, while last year they scraped into the Europa League.
"As a fan I am very disappointed. This was a campaign below anybody's expectations," said the man who took charge in Serie B after the Calciopoli scandal of 2006.
"It's a shame, as after the descent into Serie B we reached the Champions League twice. Something must've gone wrong this time.
"Will I go to see Juve in the stadium? No, never again."
