Newcastle owner Mike Ashley could be ready to listen to genuine offers for the club amid interest from China.
Reports on Monday suggested there has been fresh interest in United, who won promotion back to the Premier League at the end of last season, from Asia.
The Magpies were not commenting on the matter, but there was no outright dismissal from sources on Tyneside either, which there has been in the past.
It is not the first time a potential buyer has expressed an interest in the club, bought by Ashley for £134.4million in April 2007.
