David Lampitt has revealed Pompey have been searching for a new training ground.
But he expects Eastleigh to remain their home in the short-term.
Steve Cotterill’s men are currently based at the Wellington Sports Ground.
In the past, projects to construct state-of-the-art facilities at, firstly, Titchfield and then Gosport have fallen through.
A desire to bring Pompey’s training facilities back to the city has seen Lampitt scouring for alternatives over the past six months.
Yet finances and a lack of available sites has ensured he has drawn a blank.
And the Blues’ chief executive is now focusing on staying in Eastleigh for the time being.
He said: ‘In the past six months or so we have had a good look around at the feasibility of various other training ground options.
‘I have always been quite keen on bringing the training ground back closer to home.
‘The unfortunate reality is land on this island is a premium commodity.
‘There just aren’t that many sites where there is real opportunity and a feasible opportunity to put a training ground site on the island.
‘We are continuing that assessment and will continue to look at various options and various sites that may become available.
‘But in the short-term, the manager is very happy where he is and I think we will continue with the training ground where it is.
‘When the club does get back into a position where we have financial choices or, indeed, some investment, part of that investment can be put aside for the infrastructure of the club.
‘Whether it be ownership of a proper long-term training facility or improving the infrastructure of the stadium itself, they have to be big priorities for the long-term future of this football club.’
Lampitt revealed the training ground latest at a supporters’ meeting at Fratton Park earlier this week.
He also told fans the club does not actually own the proposed Titchfield and Gosport sites.
He added: ‘Titchfield is a site owned by a company that is officially owned by Sacha Gaydamak.
‘It is not in the ownership of the football club.
‘With Gosport, the land was never owned by the football club or anyone associated with the football club, but there was a project to develop a training ground.
‘My understanding is there was an option available to the club to take that forward and that option has now elapsed.
‘Realistically, the level of investment required to completely redevelop the site is prohibitive and something in the short-term we will not look to be doing.
