The 52-year-old, a former Juve player, was appointed as a director of the Turin club one year ago.

A former coach of the Italy under-21 side, Tardelli cited differences with other board members as his reason for leaving.

"I agreed to join with the hope that I could make many changes, but I understand that was not possible," he said.

Tardelli, who is currently in Holland watching the under-21 European Championships, said he will formerly hand in his resignation as soon as he returns to Italy.

Last month Juventus won promotion back to Serie A after spending a season in the second division following their demotion for match-fixing.

At the end of the campaign, Didier Deschamps quit as coach and was replaced by Claudio Ranieri.
