Defender Steve Finnan has admitted that not being paid on time for the third time this season is beginning to have a negative effect on the Portsmouth players.
The crisis-torn Fratton Park outfit have promised their players that December's salaries will be in their bank accounts on January 5.
A club statement cited a 'short-term delay' in the processing of funds for the third missed payment date during a turbulent season which has seen the Premier League's bottom club pass between three different owners.
However, despite the latest explanation, full-back Finnan claims the precarious nature of the club's finances is beginning to have a negative effect in the dressing room.
Earlier in the week, Pompey denied that they had been issued with a winding-up petition by Her Majesty's Revenue and Customs over unpaid taxes.
The troubled south coast club are also operating under a Premier League transfer embargo.
"The players obviously talk about what is going on – about getting paid – but as players we have to get on with our job for the club and hopefully things can resolve themselves, but I think no-one really seems to know what is going on," said Finnan.
"It worries us, it is not nice for the fans, they have obviously been supporting the club for a long time – it is just not fair on them.
"For the players it is the same – we want to play for the club.
"It concerns everyone involved, hopefully it will get resolved, but the players have to keep fighting away."
