First in Hong Kong and Singapore, then New York, it has seemed the Glazer family have been looking to raise additional capital through a partial sale of the club.
It is estimated the debt incurred during their leveraged takeover in 2005 has so far seen in excess of ?500million taken out of United to pay assorted fees and charges. And within their prospectus, it was admitted the club's present debt of ?423million could hamper them in the transfer market.
Though manager Sir Alex Ferguson launched another passionate defence of the Glazers over the weekend, even moderate United fans are bewildered as to how a club who attract in excess of 70,000 supporters to every home game - and have greater commercial income than most clubs manage in total turnover - can struggle to sign the best players.
More militant strands of that support, who have maintained a hostile stance towards the Glazers throughout their time associated with the club, are sensing a weakness.
With market conditions not improving and reception to a highly complicated IPO - that would bring in two classes of shares and effectively leave the Glazers in total control and require a new Manchester United company to be based in the Cayman Islands - said to be lukewarm, MUST have launched another attack.
"We now call on the Glazers to come back with a full flotation of Manchester United with a single class of full voting shares," MUST chief executive Duncan Drasdo said.
"Should they choose to do this, with no strings attached, we would support such a flotation wholeheartedly and encourage the global fan base of Manchester United to seize such an historic opportunity to secure a meaningful fan ownership stake where the priorities of the club are the same as the fans - not absentee owners."
It seems highly unlikely MUST will get their wish. Indeed, there are also reports that road-shows to publicise the IPO will be held, possibly as soon as Friday.
The absence of United chief executive David Gill from the pre-season tour of South Africa and Asia is an indication that might well happen. It has even been suggested the club could price the offering at some point in the week commencing August 13.
