Steve Cotterill expects Tal Ben-Haim to remain at Pompey beyond the transfer window.
And he is insistent the rest of his players are also currently not for sale.
There are eight days remaining until the transfer window slams shut.
Clubs in all four divisions have until 11pm on Wednesday, August 31 to complete their player deals.
After that, every league but the Premier League will be allowed to trade purely in emergency loans.
In the meantime, Cotterill is eyeing bringing up to three new faces to Fratton Park.
However, concerns remain among fans that players may be sold to generate additional transfer funds.
Ben-Haim would be one of the most likely candidates to depart.
The Israel international still commands a reported £36,000-a-week salary and has undoubted Premier League credentials.
He has impressed since the club ban was lifted on him in July which enabled him to play for Cotterill’s side.
And the Blues boss is confident both the Israeli defender and the rest of his players will be at Fratton Park come September.
Cotterill said: ‘There might be something happening with players coming in this week. I don’t know yet.
‘We’ve got another eight days or so and we’re looking to do one or two things.
‘As for players leaving, we’ve not had any interest in any of our players
‘But nobody is for sale as far as I’m concerned.
‘I’m preparing for Tal to be here. I haven’t spoken to anyone about Tal.’
So far, eight players have arrived at Pompey during the transfer window, the latest being Erik Huseklepp.
That has left Cotterill with a squad of 19 to choose from.
