Middlesbrough chairman Steve Gibson believes Glazer should be given time to prove himself.
"I don't understand the hysterical response," said Gibson.
"I have watched with some distaste what has gone on outside Old Trafford. I can't see that it's football to burn an effigy of a man that no-one knows and has never met. He is not doing anything illegal, he is working perfectly within his rights, but it's given one or two nobody's an opportunity to be somebody's by expressing anger against a man they have never met. It's not civilised and it's not football. I hope it calms down and quickly because it's not good for the image of the game."
"Anybody who is prepared to put that amount of money in deserves the opportunity to be heard and to get about his business. I don't know what the future of Manchester United is, but he has his own plans and he has the right to develop those, and time will tell whether it's successful or not."
The rights and views of supporters clearly don't count for Mr Gibson and his ilk.
City financier Keith Harris believes that Galzer's bankers should be worried:
"You'd have to be worried, but not as worried as Malcolm Glazer's bankers," suggested Harris.
"There are graveyards littered with bankers who have made mistakes, although I'm not suggesting they haven't done their homework, but at the minute they will be scrabbling to make sure they can get control of the assets at Old Trafford. That's the physical assets and the human assets, which is the only security they have in case things go wrong, like they can sell the ground and the players."
