Paul Cook expects Ben Davies and Brian Murphy to complete their Pompey moves in the next 24 hours.
And the duo will go straight into his squad for Saturday’s curtain raiser against Dagenham & Redbridge.
The Blues have until noon tomorrow to register the pair if they are to be considered for their first fixture, a deadline Cook is confident of meeting.
Davies to set to play at right-back against the Daggers, while former QPR keeper Murphy will challenge Paul Jones for a starting spot.
In addition, Cook is also seeking to recruit another right-back, a central defender and a striker before the end of the transfer window.
For the time being, however, Davies and Murphy are on their way.
Cook said: ‘There will be positive news announced about Ben and he will be in the squad for Saturday.
‘Hopefully we can also have something tidied up with Brian in time for the game.
‘We are after more players, we are in the market for players, but they have to be quality.
‘It’s quite funny that one or two players who turned us down have now come back to us – we have now turned them down!
‘That is how I work, that is the way I want to manage, and I want people to know that when doing something we will do it seriously and see it through.
‘We are short of a right-back at the minute. We would like to bring another centre-half in, we would like to bring another striker in, and we are looking, we are active, we have money to spend,
‘Hopefully we can excite our fans with another good signing. I want the league to feel we are going to be strong and if you can send those messages out then send them.’
In terms of goalkeepers, Michael Poke is presently on loan at Eastleigh until January.
However, the Blues possess a 24-hour recall for the 29-year-old who has yet to make a first-team appearance since arriving from Torquay in the summer of 2014.
Meanwhile, Academy stopper Alex Bass has featured in Pompey’s past two friendlies – most recently the 5-0 victory at Burnham on Tuesday night.
Now Murphy, who has made 22 Football League appearances since January 2010, is set to be on the Blues’ books.
Cook added: ‘I would like a goalkeeper on the bench. I would not go without one and I wouldn’t mind if it was a young lad at times.
‘With Michael Poke it’s too long without playing, if you are going to get put in then you are not ready.
‘Why would you want to sit on a bench for eight months? I don’t understand it, our lads must play football so what we have got to do is juggle it and balance.
‘My ideal one would be to have a second one out on loan playing like we have now and a young kid on the bench.
‘Then the likelihood is we can recall our other keeper who is now match-fit and playing games and goes into our team, no problem.
‘That is the logic, other people think you are bombing them out but it doesn’t work like that.’
