Shareholders United, the influential fans' group who have campaigned so vigorously against Glazer's involvement in the club, were quick to urge Gill to take a hard-line stance against the American.
"We hope the board will not waver in their decision to knock back Malcolm Glazer's bid," said SU spokesman Oliver Houston.
"That decision was based on sound financial principles. It would have plunged the club into debt and was clearly not in the best interests of the existing shareholders.
"They should not flinch one iota from the decision, which was 100% correct.
"Malcolm Glazer has now thrown his toys out of the pram but no-one should be surprised. This is how he behaves. This is why we are so uncomfortable with him being such a large shareholder.
"He doesn't do dialogue, comprimise or openness. He wants to ride roughshod over Manchester United but we don't want him and we will pursue any legal means possible to keep him out."
And more:
"No champagne corks are popping as far as we are concerned, although this is vindication of everything we have been saying.
"If even his own camp are running away from him I don't know what more we have to do to persuade the world that this bid was bad.
"Malcolm Glazer still has a 28% stake and still needs a way out and there may be other banks out there who will back him. He could also sell to a single buyer with similar predatory intentions and we must remember that this campaign is about 'not for sale', not to Glazer and not any single individual.
"We have been cautioning people, particularly Manchester United fans, against getting too carried away because we have been through this before.
"Glazer appears to be dead one minute and then he comes back from the ashes like the character in the Halloween films. You think you've killed him off with a shotgun blast or you chop his head off, but he still comes back for more."
