Vidal has been heavily linked with a switch to Old Trafford this close-season, with new United boss Louis van Gaal keen to take the Chile international to the Premier League.
The 27-year-old is an integral part of the Juve team who have won three successive Serie A titles since his arrival from Bayer Leverkusen in July 2011.
Juve are keen to keep Vidal in Turin, but the player himself - who helped his country reach the last 16 of the World Cup - appears to be keeping his options open.
"I've heard about the rumours, but I haven't spoken more about this subject," Vidal told La Tercera in his homeland.
"I'm enjoying my holidays, and when I return to Italy I'll see what happens.
"I'm very calm, but anyone would love to play for one of the biggest clubs in the world."
