Talk of the 50-year-old being interested in a Premier League job intensified this week with news that he is taking an intense course in learning to speak English.
The former Cagliari and AC Milan manager also suggested prior to Juve's 3-0 win over Sampdoria that he is unsure what next season holds for the club.
"I have a contract until 2020 and I am happy here. I am in harmony with the club," he told Mediaset Premium. "I go on vacation when the transfer window opens because I trust the club completely.
"We still need to meet some objectives. If we don't win the Scudetto and Coppa Italia they might not still want me. We'll talk it over the way we always do, every year. There's no difference."
