United have applied to be listed in the US in the hope of raising US dollars 100 million (?64million) from selling shares in the club. But while the Glazer family have structured the plan to ensure they retain priority voting rights over any new investors it could ultimately open the door to the Americans relinquishing control.
"Most clubs are available at a price if the truth be told," Karish Andrews, senior associate in the Sports Group at Lewis Silkin LLP, told Press Association Sport.
"There is only possibly Manchester City and Chelsea where there is no amount of money when the owners would be inclined to sell."
Andrews believes the decision to list on the New York Stock Exchange is finally an admission by Malcolm Glazer that he saddled the club with too much debt.
Proceeds from the sale will go to pay off an unspecified portion of United's ?423million debts which were loaded on to the club when the Glazers bought it in 2005. Interest payments and associated costs on those loans have amounted to more than ?500million in interest.
"It is an admission by the Glazers," said Andrews of the decision to float the club after a similar plan in Singapore last year was halted because of the volatile global economy.
"They have always not taken responsibility for admitting their takeover saddled the club with debt and massive interest payments. From what I have seen in the risk factors they have admitted that has been the case."
Andrews said supporters, who have been opposed to the way the club's debts have risen since the takeover, should welcome the latest move.
"I think Manchester United fans will appreciate that the Glazers have come clean and admitted that has been an issue for the club," he said. "I think they should see it as a positive step. They (the club) have said the sole purpose of raising the money is to pay off the debt simply because of high interest payments."
