Michael Appleton will next week push for the loan spells of George Thorne and Joe Mattock to be extended.
Their emergency loans from West Brom end on January 2.
Both have impressed as first-team regulars during their time at Pompey.
As a result, Appleton is desperate to keep them at Fratton Park longer.
The Blues boss has yet to broach the subject with Baggies boss Roy Hodgson.
But he fully intends to raise the subject next week.
He said: ‘I have had brief conversations with Roy to let him know how the lads are doing.
‘But in terms of extending it, nothing has been broached yet.
‘Maybe conversations will be held next week over whether it is a possibility.
‘I think they knew from day one that my thoughts were that we would like to keep them longer.
‘I’ve just not had the conversation yet to back that up.
‘Whether West Brom will allow me to do that is a completely different scenario.
‘It depends on how well their team are doing at the time.
‘I will definitely ask, though.’
The pair have featured in Pompey’s past three matches.
That has coincided with an upturn in form, with two wins and a draw during that period.
Mattock has dislodged Tal Ben Haim at left-back and has become a reliable performer.
Meanwhile, teenager Thorne has settled into the centre of midfield alongside Hayden Mullins.
And Appleton has been delighted with their contributions.
He added: ‘The pair of them have done very well.
‘They have raised the performances of other players in the team
‘Probably two or three of them have been given a new lease of life.’
