David Lampitt has revealed he is ‘hopeful’ of more new faces arriving at Pompey before the end of the week.
The Blues chief executive is under no illusions Steve Cotterill’s squad size urgently needs bolstering.
He is continuing to pursue his manager’s wish list ahead of the season’s opener at Middlesbrough on Saturday.
As it stands, five players have arrived at Fratton Park this summer.
However, there have been no new additions over the past three weeks.
But Lampitt has reassured fans the club are doing everything in their power to close in on other targets.
And he admitted something could happen before the week is out.
He said: ‘Undoubtedly, we want things sorted as soon as possible.
‘Obviously, we have until the transfer deadline on August 31 but the reality is we need players in sooner rather than later.
‘There are some things we are working on. These are things we hope are do-able within the next week.
‘I cannot guarantee it. It is not as simple as that, but we hope to succeed.
‘There are always three parties involved in transfers and it needs to reach the stage where everyone is happy.’
Pompey continue being linked with a string of names.
However, in keeping with club policy, Lampitt has declined to comment on them.
He added: ‘It is completely understandable fans want to know all about transfers but, as always, it is important for us to operate with a degree of confidentiality and discretion.
‘If our transfer targets reach the public domain it could push up prices.
‘We don’t want to deprive fans of information but it is important to protect the club’s interests.’
