The man tasked with finding a buyer for Newcastle has already been inundated with enquiries.
Monday night's announcement that the club is officially on the market has set City lawyer Andrew Henderson's telephone ringing, Press Assoction Sport reported, as owner Mike Ashley targets a deal before Christmas.
Henderson and his team are sifting through calls in a bid to weed out time-wasters from genuine candidates.
PA Sport reported non-disclosure agreements with four interested parties have been signed, while speculation has been rife in recent weeks that Amanda Staveley could be ready to make a move.
Staveley, who played a key role in Sheikh Mansour's takeover of Manchester City in 2008, is said to control around £28 billion of Middle East money through PCP Capital Partners and is reportedly looking to invest in an English top-flight club.
