PROTEST: John Brown urged Rangers fans to stick together
The show of strength came on the day former Rangers defender John Brown, who quit his role as a scout rather than transfer to the chief executive's newco, urged him to sell up to supporters.
He told fans outside the gates: "How do we get them out? We starve them out." He added: "Stick together. Don't buy your season ticket."
Fans are also concerned over another development.
Sevco, the Rangers takeover consortium, has transferred Ibrox, the nearby Albion car park and the Murray Park training ground near Milngavie, East Dunbartonshire, to a separate firm, Sevco Scotland Limited.
The new set-up, whose sole director is Mr Green, is separate from the London-based Sevco 5088 Limited newco which was due to receive the club's assets as previously identified by administrators Duff & Phelps. Sevco had also formed a new firm for Rangers from the ashes of the administration-hit previous one for £5.5 million.
The money is thought to be in the form of a loan to the club after Mr Green paid a nominal sum for the now worthless shares from former owner Craig Whyte.
A club spokesman said: "For the avoidance of doubt, Ibrox and Murray Park are the property of The Rangers Football Club, which at present is registered as Sevco Scotland Ltd until a name change is given formal approval.
"Sevco Scotland was formed to ensure that if the formation of a new company was required in the event of a CVA being rejected, then the club's corporate entity would be a Scottish registered company, as it has always been."
A statement issued by the Rangers Supporters Trust said that it was developing a fan investment vehicle that could ensure fans can be part of the club's future.
"In the interest of unity we shall be consulting with our sister fan organisations and those parties (such as John Brown's consortium) who have the long-term interests of the club at heart before a formal launch," they said. Mr Brown said: "The Rangers fans worldwide are behind this.
"They want to buy our club so that every fan worldwide owns their own club. Every fan will be given one vote.
"If they invest, we will set up a bank account and all the season-ticket money can go in there.
"Gone are the days of the money that we spent; it is going to be handled differently this time."
Meanwhile Morton became the latest club to object to a newco Rangers taking a place in the Scottish First Division.
And Rangers legend Sandy Jardine accused those players who are aiming to leave Ibrox for free of "greed" after they refused to transfer their contracts to Mr Green's newco.
