Steve Cotterill has refused to rule out the possibility of new faces on Pompey’s American tour.
The Blues have another eight days left in Charleston before returning to England.
In the meantime, Cotterill and David Lampitt are continuing to pursue a number of targets to strengthen the squad.
For Pompey’s manager, being out in America does not hinder his chances of recruiting.
The amount of time he has spent on his mobile phone so far during his stay is testament to that.
Chief executive Lampitt is also back in England attempting to tie up deals and add to the 15 first-teamers.
And Cotterill believes any new signing could yet join up with the team in America before the tour is out.
He said: ‘I had coversations yesterday, on-going conversations with people back home trying to sort something out.
‘You never know, if we drop lucky with any of those targets maybe they can be out here in the latter part of the tour.
‘It doesn’t matter where you are in the world, with the luxury of mobile phones everybody is contactable.
‘Just because we are in America it doesn’t mean players can’t be signed. That is not the case at all.’
A striker remains the priority of the Blues boss.
He is also eyeing recruiting in the full-back positions and the centre of midfield.
While he has made no secret of his desire to bring in another central defender following the unsuccessful pursuit of Ian Evatt.
So far there have been five summer arrivals – David Norris, Luke Varney, Stephen Henderson, Greg Halford and Jason Pearce.
Meanwhile, Hermann Hreidarsson has penned a fresh 12-month deal and Tal Ben Haim is available once again and earmarked for a regular right-back berth.
However, Pompey’s manager is under no illusions more bodies are required.
But he is unsure how close he is to sealing them.
He added: ‘Whether anything will come off soon I don’t quite know.
‘There is money involved and there are other clubs involved, so a few things to consider.
‘Obviously getting somebody in soon is something we’d really like but we’ll just have to wait and see.’
