Nadir Ciftci is to quit Pompey at the end of the season.
Blues boss Steve Cotterill has revealed the 18-year-old yesterday dropped the bombshell he will not be signing a new contract when his current one expires in summer.
A fresh deal had been on the table for the last four-and-a-half months in an attempt to keep the forward at Fratton Park.
But Cotterill says Ciftci has no intention of penning it.
The body blow comes on the eve of Pompey's clash with Burnley tonight.
Cotterill is hoping to bring in a fifth loanee to bolster his injury-and-suspension-hit squad for visit of the Clarets.
In the meantime, Ciftci may have talked his way out of being involved.
Cotterill believes the Dutch-born Turkish striker – who will effectively become a free agent at the end of the season – already has a destination lined up.
It is another body blow as the Blues boss continues to try to assemble a talented squad.
After joining Pompey's Academy from Dutch side Den Haag in 2007, Ciftci – who has been watched by Turkey manager Guus Hiddink in recent months – has broken into the Pompey first team this season.
Cotterill said: 'I don't think Nadir will be staying here from a conversation we had yesterday morning.
'It's just amazing when you become a bit of an international and something happens.
'There might be a few people in his ear-hole, which is why perhaps he hasn't signed his contract. But it all comes out in the end in the wash.
'The contract has been there for four-and-a-half or five months. From what I have been led to believe he has something lined up.
'There have been lots of excuses (as to why it's not signed) and I think, potentially, the boy has been ill-advised.
'But still, that's what happens these days.
'He didn't tell me – you find out these things in the end. That's okay, I just know I haven't got to now give all the time I was giving him.
'I can now give it to the Joel Wards who want to stay here.
'I gave him his break but that doesn't seem to matter much these days.
'Maybe I don't have to pick him now. It's something you have to look at.'
Should Ciftci leave in the summer as planned, Pompey will not receive a transfer fee.
Instead, they would get 'training compensation' in recognition of his time spent on their books.
Cotterill, left, added: 'I don't think he'll go in this transfer window.
'I think probably what will happen is it could all have been arranged.
He will go at the end of the season and there's a training compensation.
'That means they can then end up giving us less money than they would do buying him.
'I don't know where he's going.'
Cotterill is hoping to complete another loan capture before tonight's match.
The Blues have one slot remaining and the Pompey manager is desperate to push it through in time for Burnley.
He said: 'There is another loan we are still waiting on.
'We have waited now a couple of weeks on this loan and now it is getting near crunch time, really.
'We could do with having that loan in by today.
'I don't know. It's in the hands of the other club.
'Today could, unfortunately, be the lightest we have been.'
