Steve Cotterill has admitted he is unsure whether there will be any further Pompey additions before the transfer window closes.
The arrival of Markos Futacs on Friday took the number of close season recruits to nine.
That lifts Cotterill’s squad up to a more healthy 20 as he plots to negotiate the long season ahead.
As it stands, the Blues have yet to dip into the loan market.
At the end of last week, Cotterill indicated he was still pursuing two other players to strengthen even more.
Time is running out on those fronts with Wednesday’s 11pm transfer deadline looming.
Pompey’s manager remains eager to bolster his squad before then, though.
But, at present, he is uncertain whether that is now possible.
He said: ‘I don’t know at the moment whether there will be any more coming in.
‘It depends on how much money we have – or if we have any money left.
‘That’s how it stands. I don’t know if we have any money for it. I will need to wait and see.’
Even once the transfer window has closed, Pompey can still utilise the emergency loan window.
That method allowed them to sign Liam Lawrence after the failure to register him in time as a permanent deal last year.
The emergency loan window opens seven days after the transfer window closes.
By that stage, Premier League clubs will have finalised their 25-man squads, clarifying the future of many of their players.
That will enable Football League clubs to swoop on those left out.
A player can be signed on an emergency loan for a maximum of 93 days.
