Steve Cotterill believes he has done all he can to keep David Nugent at the club.
The Pompey forward capped a good campaign with his 14th goal of the season in Saturday’s 1-1 draw at Scunthorpe.
But it appears increasingly likely that it was his last appearance for the club he joined for £6m in 2007, with his current contract set to expire next month.
Cotterill is keen to keep the former Preston man as he attempts to rebuild his squad for next season.
But the Blues boss remains philosophical on his chances of persuading Nugent to stay.
Cotterill said: ‘He’s not priceless because he may be here and he may not be here.
‘If he’s not here, we have to find someone else who will be priceless to us.
‘We just need a few more priceless players next season.
‘I really don’t know the answer on whether he will come back.
‘Everything I could have possibly done to keep him here from a football manager’s point of view, I have done.
‘There is nothing left for me to do. If I was to phone David Nugent in a week’s time, I haven’t got anything more to say to him than I already have.
‘What will be, will be.’
Cotterill knows he needs more attacking-minded players next term, with Danny Webber already told to find a new club.
He said: ‘David is certainly a player you would like to have and to build on.
‘But maybe it is a time to freshen things up as well.
‘I’ve said all along that we’ve struggled to score goals.
‘We have scored six goals in 12 games – that’s half a goal per game and I’ve never won a game with half a goal.
‘That’s not enough.’
