Portsmouth's executive director Mark Jacob wants everyone at the beleaguered club to unite as he attempts to help revive Pompey's fortunes.
Fans are growing increasingly restless as the never-ending bad news surrounding the club refuses to disappear.
A delegation of supporters will march to the Fratton Park ground before the game against Birmingham City, while an open letter will be presented to Pompey officials expressing their concerns about the current state of the club.
However, Jacob said:"We need everyone to pull together, from the boardroom to the playing staff to the supporters to the whole community.
"We need to get behind the team tomorrow and be united to ensure the survival of the club in the Premier League.
"We have worked hard this week on the transfer embargo and the Inland Revenue issue and we are hopeful of good results with those. But these are mere pieces of a jigsaw and we have got to fit this jigsaw together.
"There are going to be times when the pieces do not fit and we do get let down and do get disappointed.
"But we have to ensure that at times like that we are strong enough to pull together as a club and community whereby we ensure every future piece we put into that jigsaw makes us stronger. That's crucial.
"The embargo is one piece of the jigsaw, the dispute with the revenue is another piece of the jigsaw, sorting out long-term financing is another piece of the jigsaw, as is the stadium redevelopment.
"These all take time, there is no time line when these can and will happen.
"We must stick together through these times."
