Businessman Scott Galloway has claimed it would cost between $10m to $50m (£8m to £40m) to become a "legitimate part" of the ownership group at Rangers.
The professor of marketing at the New York Stern School of Business made the statement as he revisited his scrapped plans to invest in Rangers.
Galloway - who is also a best-selling author - said last year that he had rounded up a group of 14 of the wealthiest Scots in the United States to lead a plan to take over at Ibrox.
However, he axed the plans for the US-Scottish consortium move after being warned against becoming the "most hated person in the United Kingdom" by a close friend.
Now, Galloway has invested in Colombian side La Equidad alongside Wrexham backers Ryan Reynolds, Rob McElhenney and Hollywood icons Eva Longoria and Kate Upton.
Discussing the move to invest in the Bogota club, Galloway explained that he was not in the "weight class" to invest in Rangers as he cited a huge financial cost to become a key player in the ownership at Ibrox.
"I've always wanted to invest in a soccer team," said Galloway on the Prof G Pod. "I love football, I recently went to a PSG game with my eldest.
"We've joked about it and laughed about it, but I'd enquired about investing in Rangers in Glasgow.
"But quite frankly, I'm just not in that weight class.
"Rangers, you would need to come up with an eight-figure sum of money.
"You need to come up with $10m to $50m (£8m to £40m) to be a really legitimate part of their owner group.

"So that's out of my weight class, much less a Premier League team who are now going for billions.
"So this was a fulfillment of something I've wanted to do for a long time.
"I want to take my friends and my sons to the games. That was the initial impetus, if you will."
Previously discussing his plan to invest in Rangers as part of the US consortium, he said: “I got together the wealthiest, most famous Scottish people in the US, about 14 of us, and said lets go buy Rangers FC - because it's a publicly traded company. I had it all figured out, a £10million convertible note.
"Then a friend of mine who is a famous Scottish historian said ‘you’d be the most hated person in the UK'.
"He goes 'you know nothing about football, you’d be some American idiot over there’ and I was like yeah you’re right.
"He is like 'just go to Rangers games, what are you thinking?”
