The Glazers are not seeking to sell Manchester United, the club maintains.
The Daily Mail says United sources insist the club is not for sale following speculation over a takeover bid by Saudi Arabia's Crown Prince Mohammad bin Salman.
The Saudi royal family, worth an estimated £850billion, are understood to be interested in buying United from the Glazer family to rival Abu Dhabi's ownership of Manchester City.
The club already have a connection with the oil-rich Gulf state after announcing a strategic partnership with Saudi Arabia's General Sports Authority last year. Speculation was fuelled after it emerged that United co-owner Avram Glazer is due to fly to Riyadh for an investment conference next week, although a number of prominent business leaders have already pulled out over Saudi Arabia's alleged involvement in the disappearance of journalist Jamal Khashoggi.
However, it's understood the American owners have no wish to sell a club they bought in 2005 for £790m, even though United are now valued at between £3bn and £4bn.
