Liverpool boss Brendan Rogers was visibly disappointed after his side suffered their third defeat in a row.
Defeats against Newcastle, Chelsea and Crystal Palace leave the Reds in a disappointing 12th place in the English Premier League table, 18 points from leaders Chelsea.
"We made a really good start to the game, Rickie Lambert got his first goal with a terrific finish. We made the perfect start but failed to manage the game at 1-0," Rodgers told BBC's Match of the Day.
"We are very, very disappointed with the performance and the result and as the manager it is something I need to take full responsibility for.
"Our confidence is not high at the moment, we do not see speed in the passing and we have to work even harder.
"It is a difficult moment, a tough time because of the results and we have to make sure we retain one focus - that of getting better and improving and very, very quickly because games come thick and fast.
"The confidence is low - we need to find a way. This has been a new phase - a lot of games, a lot less preparation time.
"We can't complain - we have to find a way to get results and show real size and power of the club. We need to get back to the basics."
Rodgers was praised for his work at the club last season but some Liverpool fans have been calling for the manager to be sacked after a run of negative results in England and Europe.
"I'm not arrogant to think I'll be in a job through anything," Rodgers said.
"You have to win games and results. I've got a great communication line with the owners - we are honest and open with each other. I know that we have to get results and perform.
"The owners have to see development on the field - our development has been very good and fast. I will only ever do my best - I need to fight even harder and take responsibility.
"He's [Raheem Sterling] played a lot of games. There is a lot of pressure on the young player. He's not an unknown and is a marked player.
"Raheem's confidence is not quite as high and the intensity not quite as high. He's an outstanding talent - he's going to have little spells like that.
"Mario [Balotelli] came back from the Italy squad and it was still sore [groin] - we will assess that over the next few days."
