Michael Morrison admitted that Pompey’s confidence has been affected by their poor run of form.
A resounding 3-0 defeat at Bolton sent them tumbling down to 15th position in the League One standings.
Goals from Dion Charles, Kieran Lee and Eoin Toal ensured Wanderers came out on top against the Blues for the second time in a week.
And Morrison knows that plenty of hard work is needed in order for Pompey to get their season back on track.
The defender said: “We had a slow start to the game, but seemed to have come to terms with that and we had two big chances.
“I had a really good one – I hold my hands up to that – and the difference was there in both of the boxes.
"You can see that there’s a confidence issue at the moment. It would be silly to say otherwise, but we have to stick together to come through this bad moment."
“We came out for the second half and make a mistake. They punished us and it was a long afternoon after that.
“The sucker-punch made it 3-0 and it’s ultimately a really frustrating and disappointing day for all of us.
“We know the fans have come a really long way to support us and we’re sorry that we’ve let them down.
“If we’re being honest, it’s obviously pretty low. We have to look at ourselves and work hard to get back up.
“There’s a free week now, so we can try to put everything right and solve the problems that we’re having.
“You can see that there’s a confidence issue at the moment. It would be silly to say otherwise, but we have to stick together to come through this bad moment.
“It doesn’t need to be pretty at the moment – we just need a win. We know the quality is here, although you can’t just keep saying it. We have to translate it onto the pitch.”
