Hayden Mullins has revealed Pompey are finding it hard to cope with the loss of their team-mates.
Erik Huseklepp and Liam Lawrence have both been shipped off on loan in recent weeks as administrator Trevor Birch attempts to find a new owner and the funds to get through the season.
Huseklepp joined Birmingham and Lawrence signed for Cardiff – both on loan until May – as Pompey slashed the wage bill and received some vital income from loan fees.
But while it was necessary, it has left Pompey’s resources stretched to breaking point and has also affected the remaining players.
Mullins said: ‘It can be hard not to get beaten down by things. First it was a points deduction and the wages thing, then you start losing good players like Erik and Liam.
‘Losing players like them is a big blow and then you have suspensions and injuries to deal with.
‘It’s tough but you just can’t let it drag you down. You just have to distance yourself a bit from it when you can.’
Mullins has yet to miss a game this season and is among a contingent who are playing through the pain barrier to get through matches because Blues boss Michael Appleton simply has nobody else to call upon.
The Pompey midfielder said: ‘That’s the problem.
‘When you start getting knocks and things, you have to play through them.
‘We’ve got a small squad as it is but then sometimes we are left with six or seven training.
‘But we’ve got some tough boys who will keep going.
‘We are professionals and we have to concentrate on doing what we can and trying to win a few games.’
