Steve Cotterill is targeting a goalkeeping rival for Jamie Ashdown.
The Blues have released back-up Darryl Flahavan after the 32-year-old spent the season at Fratton Park.
Flahavan – brother of ex-Pompey keeper Aaron, who tragically died in a car accident in 2001 – never made a first-team appearance, although featured in three friendlies during the campaign.
Now Cotterill is looking elsewhere as he bids to provide crucial competition for number-one Ashdown.
He said: ‘Darryl was on a contract until the end of the season and he is now going.
‘I just wish him all the best and, hopefully, he will find somewhere.
‘Instead, I’m looking at someone I just feel will put a bit more competition on to Jamie.
‘I want somebody who has played at a good level and have a couple of ideas. One would be a free transfer I think we could get. It’s very important to have competition all around the pitch.
‘It’s something we have not had this year and when any of them are tired – physically or mentally – or injured, we haven’t had a player I can turn to a lot of the time.
‘It’s important now we try to get a squad together who can try to push the club into the upper echelons of the Championship.
‘Jamie has played 50 games but has had a few docile matches, I think one of them was at Scunthorpe, although he wasn’t the only one.
‘But, for sure he needs competition.’
Meanwhile, Cotterill is closing in on adding another keeper to the youth set-up.
He added: ‘We’ve got a couple of young ones at that level, but we will be signing another goalkeeper for the youth team.
‘We are just getting that through at the moment.’
