Liverpool captain Jordan Henderson assessed that "everything went wrong" for the Reds in the 3-0 Premier League defeat to Brighton.
Jurgen Klopp's side suffered a sixth top-flight defeat of the season as Danny Welbeck added to Solly March's brace to seal a memorable win for the Seagulls at the Amex Stadium.
The Reds have now started a calendar year with two league defeats in a row for the first time since 1993, while they have also lost as many as five away league matches in a single season for the first time since the 2017-18 campaign.
They could end the weekend 10 points adrift of the top four and Henderson wants to see a reaction from his team-mates in their next few games.
"Everything went wrong from the start to the end," he said. "Brighton were better than us in all departments. It's a real low point as a team. We have to stay together.
"It's a tough moment but we need to get together, stay together and try and change things quickly. We have to try and learn and show a reaction.
"There wasn't one thing. It was numerous things and it hasn't been right for a little while now. Everybody knows that. We know we can be better.
"I'll take responsibility and the lads will. We have to try to put it right."
Asked if it was Liverpool's worst performance under the management of Klopp, Henderson said: "Probably. I can't remember another one. A really tough day.
"We're pretty low on confidence. The energy level is low. Everything. We can't feel sorry for ourselves. We have to keep fighting and hopefully we can change it sooner rather than later.
"We know we can play better and give even more. But you have to keep working."
Liverpool have an FA Cup third-round replay against Wolves on Tuesday, before a Premier League clash with Chelsea on Saturday.
