Arturo Vidal
Vidal\'s future looks increasingly like to remain at Juventus.

Manchester United's hopes of signing Arturo Vidal have taken a potentially definitive blow after Juventus included the Chile international on their pre-season tour to Asia.

The Serie A champions have yet to fully commit to keeping Vidal at the club, and have hinted they would be open to allowing the 27 year old to leave should he indicate his desire for the move.

Despite's Vidal's future being uncertain, new Juve manager Massimiliano Allegri has included him in his 28-man squad for their Asia pre-season tour, a genuine indication the club see him as part of their future plans.

Juventus face a two-week tour of Asia which includes matches against Indonesia, an A-League All Stars XI and Lions XII and Malaysia Super League Internationals.

Vidal has been at the centre of speculation all summer regarding a possible move to United, whose manager Louis van Gaal has been evasive over the possibility of new signings.

Ander Herrera and Luke Shaw have arrived this summer but Van Gaal says he will prioritise strengthening United's defence during the remainder of the transfer window.

Juventus have done little to quash speculation over Vidal's future, preferring to allow the player to comment on his own future. Amid the uncertainty, defender Giogio Chiellini said: "I am convinced Arturo Vidal will stay with us."

Club director general Giuseppe Marotta added: "(Arturo) Vidal? We already said that he is not on the market, but the player's will is decisive.

"Vidal has never said he wants to leave, and Juventus will sell him only if he were unhappy to remain. Nowadays, however, there's absolutely no reason to even be discussing this now."

The former Bayer Leverkusen midfielder has said he has no interest in moving to United but rumours have been fuelled by Juventus' vague stance on his future. Vidal still has three years remaining on his contract at the Juventus Stadium.
