The defender says that morale is still high despite their back-to-back defeats.
Having started the season well, the Eagles have lost their last three games in all competitions, losing to West Ham United and Leicester City in the league and suffering a heavy 5-1 defeat to Manchester City in the Capital One Cup.
The side are obviously keen to identify what has gone wrong in recent weeks as they seek to rectify the issue, but Hangeland says there is no obvious reason, saying instead that they need to just work hard to turn things around.
"I don't think there's anything particular that's caused it,” he told cpfc.co.uk.
“We've played some good teams and things haven't really gone well for us, so we need to keep working hard - like we always do - and we're just desperate for another chance to put things right on Saturday."
The defender also insisted that morale is still high in the squad despite their back-to-back defeats.
The 5-1 defeat to City in particular is sure to have been a blow to the side’s confidence, with them having had several chances to score in the game, but not being clinical enough with their opportunities.
Losing so heavily will have been hugely disappointing for them, but Hangeland insists the mood remains upbeat, stating that they are simply keen to return to winning ways as soon as possible.
"It's still very much a happy camp,” he added.
“We work hard and no one likes to lose - that's certainly the case with this bunch here," he said. We're really keen to put things right as soon as possible and to get some points.”
