Captain Jordan Henderson admits Liverpool are suffering a lack of confidence but insists players cannot afford to feel sorry for themselves.
The Reds were outclassed at the Amex Stadium and have already dropped 26 points this campaign, leaving them out of title contention and with an uphill task to qualify for the Champions League.
“It’s a real low point for us as a team,” England midfielder Henderson said of the heavy south-coast defeat, according to his club’s website.
“We need to stay together. There’s an honest bunch of lads in there and it’s a tough moment for us as a team, for sure, but we need to get together.
“We all know we can be better individually, collectively, everything across the board.
“And I’ll take responsibility, the lads will take responsibility to try to put it right.”
Speaking of the mood in the dressing room, the 32-year-old continued: “Not good, as you can imagine.
“Pretty low, low on confidence – you can see that when we’re playing – energy levels low, everything.
“It’s no good feeling sorry for ourselves. I’ve been through moments like this in my career and you’ve got to keep fighting, you’ve got to keep going and hopefully we can change it sooner rather than later.”
Manager Klopp accepted blame for another disappointing day in Liverpool’s stuttering season, conceding he could not recall a worse display.
Solly March’s quick-fire double early in the second half gave the Seagulls the advantage their dominance deserved, before substitute Danny Welbeck sealed a comprehensive victory.
“We need to stay together and try to change things really quickly because the games are coming thick and fast and we need to try to learn as best we can and show a reaction,”said Henderson.
“We know we can be a lot better, we know we can play better, we know we can give even more – which is the real disappointing thing.
“But you’ve got to keep working, you’ve got to keep going.
“It’s important we stay together and come through this, and it’ll make us stronger in the end.”
