Siena have told Juventus to make their move sooner rather than later if they intend to approach boss Antonio Conte.
The latter has been linked with the Juve job given the uncertainty over the future of current Coach Gigi Del Neri.
"I don't know if Juventus will call him, but I just hope that a decision is made soon as we need to start making plans for next season," Siena sporting director Giorgio Perinetti noted.
"Our President is thankful to Conte and is ready to allow him to follow his dream of coaching Juventus.
"We just want the situation resolved by early next week."
Siena will be back in the Italian top flight next term after Conte was the mastermind behind their promotion.
"Conte has done a great job here, but it is Juventus who now need to decide whether he is the right Coach for them," Perinetti added.
"I know that Juventus are a dream for Conte and I hope that he gets there now or in the future," the official added.
Conte is a legend in Turin after spending over a decade with the Old Lady as a player.
