Gordon Taylor has revealed how Pompey are exploring the forwarding of parachute payments in a bid to pay their players.
All staff at the club are yet to receive their wages for January.
As it stands, that will remain the case until a validation order is granted by the courts to unfreeze the club account.
In the meantime, the Professional Footballers Association and representative Nick Cusack are in constant touch with the Blues’ players and the club.
Taylor, the union’s chief executive, admits parachute payments are being considered as an option.
The Blues are scheduled to receive windfalls of £16m over the next two years as part of the financial package following relegation from the Premier League.
And Taylor is hopeful a solution can soon be found.
He said: ‘At the moment we are staying in touch with the club to get some funds in and look to pay the players.
‘Our representative Nick Cusack is continuing talks with all parties to try to resolve it as best we can.
‘We are looking for money revenue due to the club to try to get money owed them.
‘I don’t want to go into the current circumstances but that would be parachute payments and things like that.
‘The club has been through the mangle but the problem is a little bit inherited from the past.
‘This has been inherited difficulties coming from not the best financial propriety from the past.’
Meanwhile, Taylor has praised the players as they continue to give their all for the club.
He added: ‘They have been absolutely brilliant.
‘It has not been the best of times for a while now but it never ceases to amaze me how players are prepared to knuckle down.’
