Liverpool manager Jurgen Klopp has accused his side of only trying 95% after losing 2-0 at West Ham United.
The Reds were poor as striker Andy Carroll scored against his old club after Michail Antonio had given the hosts the lead.
Liverpool are now eighth having lost three of their past six Premier League games, and their next top-flight match is against current leaders Arsenal.
"This is not a day to be disappointed, this is a day to be angry," Klopp said.
Liverpool's next two games are away to Stoke City in the League Cup semi-final followed by a trip to League Two Exeter City in the FA Cup third round on 8 January.
They then entertain the Gunners on 13 January followed by Manchester United four days later.
"I'm really angry because we could have got so much more," he told BBC Sport after the West Ham defeat.
"But I don't want to talk about what we could have done because we didn't."
The German added: "It was not enough from my team today. The decisive moments were there, but we were not there 100%.
"We could have done much better. We had our moments, we tried, but if you fight at 95 per cent then it's not enough.
"It's my responsibility."
