Silvano Martino has confirmed that the Spanish giants have made no official enquiry for the Serbian international but did not rule out a move if something happened to eventuate.
“Real Madrid? So far the Spanish club has not contacted us," Martino told Itasportpress.it.
"It is difficult for him to leave England even if with the market open anything can happen."
Despite Martino’s comments, United are reportedly set to offer Vidic a new deal worth £90,000 a week to beat off any competition from the if the Spaniards did happen to make a bid.
