Amid strong Manchester United interest, the Chilean midfielder said there is uncertainty over whether he will remain at the Scudetto holder this summer.
Manchester United is interested in signing the Chilean, 27, with Louis van Gaal believed to be keen to bring the former Bayer Leverkusen midfielder to Old Trafford, while Real Madrid has long been linked with a move for him.
With Antonio Conte having resigned as Juventus coach and Massimiliano Allegri named as his successor, it has been suggested that Vidal may be leaving Turin this summer. But he says he has no idea where his future lies ahead of the 2014-15 season.

"It's hard to talk about another big club when you're already at a team at the top level," he told Chilean newspaper La Cuarta. "I've won three championships with Juve in Italy and I have respect for my teammates. I've heard of interest from Real Madrid as well as that of Manchester United, but these are things there that my agent is dealing with.
"I honestly do not know if my cycle with Juventus is finished. When I return to Italy I will talk with the new coach and see what happens. Now all I'm thinking about are the seven days of holiday that I have left."
Vidal joined Juventus in 2011 in a 10.5 million-euro deal from Bayer Leverkusen.
