The defender has no doubts that the Chilean will ignore overtures from the Premier League giants and admits that he was shocked Antonio Conte resigned last month
The Chilean has been heavily linked with a transfer to Old Trafford and, despite the Bianconeri publicly claiming Vidal is going nowhere, rumours are persisting that a move is in the offing.
However, his team-mate Chiellini has no doubt that Vidal will remain in Turin and insists that he has no plans to depart Juventus either.
"I am convinced Arturo Vidal will stay with us," he told reporters ahead of the Turin club's pre-season tour of South East Asia.
"My contract is not formal, but I think it’s safe to say I will be a Juventus player for a long time yet."
Antonio Conte guided Juventus to three successive Scudetti but became frustrated with decisions at boardroom level and stepped down earlier this summer.
Though Chiellini insists he is desperate to impress under new boss Massimiliano Allegri, he admits he was stunned by Conte's decision to part ways with the club after so much success.
"I totally did not expect Conte to leave," he added. "I was on holiday and there were rumours, but then it actually happened.
"After initially being shocked, we all put ourselves at the disposal of Allegri and we want to continue our winning era after three years of success.
"The fans are struggling to see it clearly and were shaken up, but they must understand that Allegri is a vastly experienced coach.
"We're reinforcing with good players and the unconditional support of the fans is important. This is still a winning team and Allegri’s arrival can even make us more unpredictable."
