Pompey have lined up a Premier League goalkeeper on loan for the season.
But Michael Appleton is still awaiting Football League permission to complete the deal.
As it stands, the Blues don’t have a single keeper on their books with pre-season starting next week.
Jamie Ashdown and Academy prospect Matt Gledhill were released at the end of last season after Appleton decided against extending their contracts.
In addition, Australian youngster Daniel Nizic, who had been trialling with the club for the majority of the last campaign, has opted to join Burnley.
Pompey’s boss has already identified the player he wants to bring into Fratton Park to serve as his number one.
He favours taking in a youngster who has experience of playing in the lower divisions.
Among those who fit the profile are West Brom’s Luke Daniels, David Button from Spurs and Norwich’s Jed Steer.
However, any prospective move has ground to a halt while Pompey await permission from the Football League to bring in their target.
He said: ‘We have got one in the bag. It has been agreed to take a goalkeeper on loan for the season.
‘The problem is until we have got permission from the Football League we cannot do anything about tying it up.
‘I’m well aware our first friendly is on July 14 and we haven’t got a keeper in the squad.
‘I might have to find someone off the street!
‘In all seriousness, the reality is we might have to play a triallist or two in pre-season.
‘People ask why Jamie Ashdown was let go but we do expect to bring players in. It’s just we cannot at the moment.’
