There were calls during the week that manager Martin Jol's position was already in danger despite just six games of the new season being played but the Cottagers turned it on to demoralize QPR 6-0 yesterday.
That result has eased plenty of pressure on the Southwest Londoners but Hangeland says there were never any cracks in the squad prior to the big victory.
"We're all in this together and everyone involved with the club can feel a bit of extra pressure when things haven't gone as well as we wanted them to," he said.
"That goes for me, the rest of the players and I am sure the manager as well.
"We're very much a united club. I think there is always a bit of frustration when we play reasonably well and don't get the results and people wonder why this is happening.
"You can see we are still a good team and can take a lot of confidence from this."
