Steve Cotterill hopes to discover next week whether he will be able to strengthen during the transfer window.
The Pompey boss is awaiting the outcome of talks held with Balram Chainrai 11 days ago.
At the London meeting, Cotterill met the joint-owner to discuss ways of maintaining the Blues' positive progress on the field.
Yet Pompey's manager remains in the dark over his ability to recruit.
Instead, he can only gaze enviably over to Hull who this week have pursued Peterborough's Aaron McLean and Leicester's Matt Fryatt.
Cotterill himself is eyeing two loan signings.
And he expects the wait to go on until next week.
He said: 'There is no news yet.
'At the moment I don't know what is happening.
'I would like to hear some good news and be able to pass that on, but let's just see how we get on in the next week and then we'll have an idea if there is anybody we can bring to the club.
'It seems like a few clubs have put their marker down.
'Hull have come out and done that in the last week with Aaron McLean, which is really interesting and obviously good for them.
'But we'll have to wait and see.'
