Portsmouth's players finally received their wages for December amid a stinging rebuke from the Professional Footballers' Association.
The club paid its players after obtaining more funds to ensure the long-running issue was resolved.
But senior PFA executive Nick Cusack warned that the club cannot keep delaying the payment of wages and was determined to try and ensure that it would not happen again.
"Portsmouth cannot carry on like this," said Cusack. "I am sure the people we are talking to are honourable and want to sort it out, but there is a lack of information about how the club is being run, how the players are being paid and whether they will be paid in the future.
"We must find out whether the players will be in this position next month, and indeed throughout the season."
Portsmouth's precarious financial position was underlined further by the fact that the club's owners only just managed to obtain funds to pay the players in the last two days.
Chief executive Peter Storrie said: "Obviously it is not the best scenario in the world to have this situation happening but obviously finance is a major problem in world market at the moment.
"The owners are trying everything they can and they obviously managed to find this in the last couple of days."
Storrie also insisted players would not be sold on the cheap in order to help ease their financial crisis.
Storrie added: "I've had one or two calls and I think one or two people think there is some sort of fire sale going on. That is not the case. If we have to sell players we'll sell them for their market price and not what people think is a knock down price."
Pompey insist they have yet to receive any interest in England goalkeeper David James but clubs have enquired about other members of Avram Grant's squad.
Pompey are reportedly some £80million in debt and will need to sell some of their stars in the current transfer window.
Defender Younes Kaboul has already attracted interest from Lyon and Manchester City while Jamie Ashdown is a target for ex-boss Paul Hart at Queens Park Rangers.
Ashdown's contract expires at the end of the season while the club would prefer to sell striker David Nugent, on loan at Burnley, rather than give the go-ahead to a further temporary spell at Turf Moor. But so far, no other club has enquired about James.
"The truth of the matter is, if the owners decide they want to sell players to bring money into this football club then that is their decision," added Storrie.
"If someone makes an offer for a player they will consider it - and there have been some enquiries. But not a single one has come for David James.
"There has been no interest whatsoever and as far as we're concerned, he will remain here.
"I admit there is interest in Ashdown and Paul Hart would like him, but we have not made a decision at this stage."Reuse content
