Pompey will finalise their retained list at the end of this month.
That is the timeframe David Lampitt is looking at to decide the futures of Danny Webber, Hermann Hreidarsson and Darryl Flahavan.
The trio are out contract this summer and anxiously waiting to discover their fate.
In addition, David Nugent has already been offered terms but has put his future on hold until the campaign has ended.
Those definitely leaving are Tom Kilbey, Marlon Pack, Richard Hughes and Michael Brown. Meanwhile, Nadir Ciftci will walk out for a club in Turkey after turning down a new contract.
Now the focus is on Webber, Hreidarsson and Flahavan as Steve Cotterill plans for next season.
And Lampitt believes such decisions will be made before the month is out.
He said: ‘Probably the timeframe will be towards the end of this month – that will be when we will make decisions about retention.
‘It is part of on-going discussions between myself and the manager but, first and foremost, we want to keep our group of players focused.
‘There are still five games to play and, from our point of view, it is incredibly important we do well.
‘The better position we are in the table means the better we are able to attract talent to the club in the summer.’
Nugent remains the burning issue.
The striker has made no indication whether he wants to remain at Fratton Park.
He will also have to accept a pay cut if he is to meet the club’s new wage structure.
As it stands, though, there will be no more talks until the season ends on May 7.
After that, it will be up to Nugent to reveal his plans.
But Lampitt is comfortable with the situation.
Pompey’s chief executive said: ‘To a certain extent, the ball is in David’s court.
‘Our desire is for him to be a Portsmouth Football Club player beyond the end of the season.
‘To be fair to the player, he has got some decisions to make and I understand that.
‘We can’t force him to do anything he doesn’t want to do and nor would we want to.
‘I want him to stay here only if he wants to stay here and be part of the future of the club.’
