The Supporters' Trust are furious at how the club is being run and how much money is being squandered on players who cannot deliver on-field success.
The FAB has responded to those claims: "Bluntly, we don't recognise the suggestion that fans are not being involved in the future of the Club.
"This goes directly against our experience. So we wanted to set the record straight.
Significantly more resources have been allocated to fan liaison than at any point in the club's history.
"Before the FAB was created there was one part-time employee devoted to supporter liaison.
"There is now a department which will number four full-time members of staff. Contrary to what has been suggested, these facts give a full and proper picture of what is going on."
FAB added: "We have had multiple sessions with club executives to work through potential proposals and provided with data to help substantiate any potential changes.
"So whilst the precise content of these meetings must remain confidential until any decisions and changes can be communicated with supporters, the idea that fans are not involved and not at a decision-making level, could not be further from the truth.
Football is a matter of opinion and expressing emotion is part of that.
"But we have to get behind our team and make our contribution to victory rather than seek chaos and division through attacks and campaigns.
The only people who benefit from Chelsea fans turning on Chelsea are fans of other clubs. If we're pulling in the same direction then 'every little thing gonna be alright'."
