Mark Catlin has revealed Pompey’s board are to choose the next Pompey manager over the next 24 hours.
But he has warned it is likely to be after the weekend before the appointment is finalised through a contract.
The Blues have so far interviewed five of the seven candidates on their short list to replace Guy Whittingham.
The final two will be seen today before the board attempts to reach agreement over the preferred applicant.
Catlin and finance director Tony Brown have attended each interview, along with various board members, although the chief executive has no input in the decision-making process.
Instead it will be left to Iain McInnes, Ashley Brown, Mick Williams, Mike Dyer, Chris Moth, John Kirk and Mark Trapani to make the final decision.
Catlin has once again declined to discuss the names of the candidates.
But he has been impressed with the calibre of those to have come forward.
He said: ‘We have been really impressed by the standard of applicants and those who have taken part in interviews as well.
‘Interviews have been taking anything from one-and-three-quarter hours to two-and-a-half hours because we want to be as thorough as we possibly can.
‘In addition, there are background checks on each candidate with their former chief executives, chairmen, players and suchlike.
‘The last meeting is this afternoon and from that moment the board will choose a candidate. That candidate will then be invited back for one final chat and at that point we will enter contract talks with them.
‘But you cannot do things in haste, which is done all too often in football.
‘It is a carefully considered process and not something to complete in a day.
‘The aim is still Monday and – with football being a weekend business – we can work over a Friday, Saturday and Sunday to get everything completed.’
