Portsmouth manager Michael Appleton believes the sale of three more players would take some pressure off the financially-stricken club.
Pompey are currently in administration and the club's creditors - owed a reported £24million - will vote on Monday whether to accept Balram Chainrai's Company Voluntary Agreement, while the Pompey Supporters Trust are still hopeful of launching a rival bid.
"If we can get three players out by the start of pre-season that will be very helpful," Appleton told BBC Solent. "Hopefully the CVA will get approved. Then there will be a period of time when Balram Chainrai takes the club over."
He added: "In that period of time I'm not sure how many players, if any, I'll be allowed to bring into the football club. I would imagine it would be a difficult period of six weeks until the season starts.
"From a motivational point of view it's a lot easier to get your squad together at the start of July and work with them from then.
"You can get them ready, gel during pre-season, work on the dynamics of the squad, get them to play how you want. I'm not going to be lucky enough to do all those things."
