Dave King claims Rangers need donations on a non-commercial basis to move forward, and should not rely on ticket sales to turn things around.
Rangers are soon to be liquidated and their place on the SPL fixture list was occupied by 'Club 12' when the schedule was released, as the uncertainty over the club's future continues.
Whether Rangers take up the place depends on whether the Scottish Premier League vote in favour of accepting a 'newco' Rangers which is set to be established by Charles Green, who has led a takeover of the Ibrox side.
On his arrival at Glasgow Airport, the former Rangers director told a number of television crews: "I really don't believe Rangers represents a financial opportunity for anyone other than an asset stripper.
"There is only one way forward for the club and that is that the club needs a level of funds which is way beyond the ability of the fans to support it with season tickets.
"There is a structured financial deficit and unless the club gets access to funders who are willing to put money in on a non-commercial basis, I think for at least three years, then I don't think the club will go forward."
King, who was the second-largest shareholder after former owner Craig Whyte, has requested a meeting with Green and is set to meet with members of a Walter Smith-led consortium.
King has not committed himself to putting money in.
"I'm able to do it, it's just a case of making sure what makes most sense for the club," he added.
"If I believe the right plan is put in place, that I think best meets the needs of the club going forward, then it's certainly something I would consider and am capable of doing."
