Fiorentina have told Riccardo Montolivo to inform them if he wants to leave the club this summer or not.
The Italy international only has one year left on his Viola deal and the club are wary of running the risk of losing him for free at the end of the new campaign.
Fiorentina offered Montolivo new terms following Gaetano D'Agostino's Udinese switch, however, they are growing impatient at his lack of urgency.
AC Milan are believed to be keen on the 26-year-old and the Viola have given the midfielder a deadline on a decision after which they will plan for life without his services.
"Montolivo's situation? It seems he's making a fool of me," explained the club's owner Andrea Della Valle.
"With D'Agostino's departure we've offered him the chance to stay, but if he doesn't want to remain he must tell us he wants to go.
"He must do it inside a couple of days."
