The 26-year-old has made an impressive start to the season and was strongly linked with a move to Real Madrid this summer.
“If (Real Madrid’s Gareth) Bale is worth 100million euros, Vidal is also worth that figure,” Juve general director Giuseppe Marotta said to Mediaset Premium.
“Vidal is a great player and this summer Real Madrid showed an interest in him but we turned it down. Selling him is simply out of the question.”
Vidal’s current contract with Juventus is set to expire in 2016.
