Portsmouth administrator Trevor Birch has said it is too early to predict with any confidence whether the club would remain in business beyond next month's deadline.
Birch, a partner at accountants PKF, announced on Tuesday that Portsmouth would be forced to close on August 10 unless its remaining senior players either reached agreement over their unpaid wages or left the club.
Striker Luke Varney, midfielder David Norris and defender Greg Halford have this week completed their moves to Leeds and Nottingham Forest respectively, while other clubs have expressed interest in striker Erik Huseklepp and midfielder Liam Lawrence.
"We're continuing to work on player exits," Birch said. "Huseklepp, Lawrence, [Dave] Kitson, [Tal] Ben Haim and Kanu are the ones left."
When asked what chances the club had of survival, Birch added: "It's too early to say. It's only two or three days since we released the deadline statement but we'll keep going."
Kanu and Ben Haim have responded to perceived criticism from Birch for refusing to compromise on their wage demands by calling on PKF to waive their fees for overseeing the club's administration.
