He told BBC Radio Nottingham: "They are extremely angry. What's happened over the last few weeks has been extremely demoralising.
"The unprecedented backlash they have had from certain sections of the media has been quite scandalous."
Trembling added: "I just can't fathom why people aren't applauding the fact that these Middle East businessmen want to invest in Notts County.
"I don't know if it's jealousy or a vendetta or pure spite and maliciousness."
The Football League board meet on Thursday to discuss the takeover by Munto Finance, many of whose investors remain unknown.
Trembling remains convinced that the takeover will be ratified.
"I met one of the owners over the weekend and they are the nicest people you could wish to meet and so genuine about what they want to do," he said.
"They are still enthusiastic about this football club and about this project but there is a real air of concern at the moment.
"I expect a 100% ratification, I don't envisage any problems and if there were I fear the consequences."
