Pompey are close to making Jason Pearce their second signing of the summer.
And Bournemouth chairman Eddie Mitchell wants any potential deal to be concluded by the weekend.
The Cherries accepted a third Pompey bid for the defender yesterday.
This was discussed at a Dean Court board meeting yesterday morning, with the green light being given.
Pearce is now expected to undergo a medical today before sealing the switch.
Pompey have long been overwhelming favourites to sign the 23-year-old.
His potential return would represent a return to the club he left in the summer of 2007 after serving his apprenticeship.
Mitchell told The News he wants any prospective transfer to be completed by the end of today – and it appears as if it will.
He said: ‘The latest is Jason is a Bournemouth player.
‘Jason is not up for sale but the way football works is if an offer came in it would be considered. Time will tell. Portsmouth have made two or three bids now and I spoke to them again yesterday. I think they are quite keen.
‘They know they will be getting a great lad. There have been three clubs bidding, a few others have been interested.
‘It will depend on the end of today what happens. If Jason hasn’t gone he will stay. If he is going it has to be quick.
Pearce was one of the star performers in the Cherries side which reached the play-offs last term. Defeat on penalties in the semi-finals against Huddersfield ended hopes of reaching the Championship.
But Pearce is destined to make the step up. And Mitchell believes the defender will prove a quality acquisition for anyone.
He added: ‘I do not think you will get a more loyal, committed, 100-per-cent player than Jason.
‘I think the only problem he has got is he can’t head straight!
‘He’s fantastic, plays every game and is club captain.
‘A lot of tears will be shed if he goes.
‘Jason leads by example, I have got a soft spot for him.
‘He’s a brave lad and what he lacks in skill he makes up in energy and enthusiasm.
‘He’s a wonderful player and I am sure he can do a great job wherever he goes.’
