That was the warning today after it was reported that Green is preparing to make a bid for control of the Glasgow giants.
The controversial English businessman fronted the consortium that bought the Ibrox club's assets two years ago.
However, the former Sheffield United official stood down as chief executive last year due to "negative publicity".
Last night one fans' protest group insisted most supporters would oppose any power grab by Green.
Sons of Struth spokesman Craig Houston said: "I don't think the majority of fans would like Charles Green returning to the club one little bit. "
The latest twist in the Rangers game of thrones comes days after it was revealed the club are to hold another share issue before August in a bid to raise £8million.
The SPFL League One champions have only offloaded 17,000 season tickets for the 2014/15 campaign - half of what they sold last season.
The Union of Fans - an umbrella group of six supporters organisations - had called for security over Ibrox and Murray Park.
And they had been urging Light Blues followers to pledge cash to Ibrox 1972 Ltd and instead buy tickets on a game-by-game basis.
But Houston believes Green taking control again would not go down well with already disillusioned fans.
And he predicted they would show their anger by refusing to part with money for season tickets in their numbers.
Houston said: "I certainly don't think he is coming back in an attempt to drive sales of season tickets upwards with the past that man has with Rangers fans.
"I think a fair few of the 17,000 supporters who have bought season tickets would be upset if he was to return."
The BBC reported at the weekend that Green had been holding talks with potential investors in Rangers last week ahead of the share issue.
The Englishman helped to raise £22m at an IPO in November 2012 after the Ibrox club dropped to the bottom tier of Scottish football.
That cash, though, has been spent amid widespread speculation over what it was used for.
The business review carried out by current chief executive Graham Wallace was scathing about the business practices of the previous regimes at the club.
The review claimed the Govan club had "mismanaged almost all of their cash reserves" and had squandered in the region of £70million.
It revealed contracts had been handed out and commercial deals struck without lawyers being present. And it stressed these were now putting the club under huge strain.
