Defender Paul Konchesky has admitted he has not yet reached the level required at Liverpool and accepted full responsibility for Sunday's 2-1 defeat at Tottenham.
The left-back was given a tough time by Aaron Lennon and was caught out of position and found lacking for pace as the winger raced through to score the winner in added time.
"I've got to up my game. Where I've played before has not been as high a standard as Liverpool, but this is a good pressure," said the 29-year-old.
Despite an encouraging performance at White Hart Lane, where the Reds dominated the first half and should have led by more at the interval, Konchesky was the one player who came in for criticism.
He added: "The fans want you to be in the top four because that's where Liverpool belong.
"Straight after (Lennon's winner) I knew that I'd have to hold my hands up, but we also had chances to win the game.
"That's part of football and we've got to try to take the positives out of the game.
"I was gutted (with the winner); being the last minute as well it didn't give us any time to get back into the game.
"But that's life, we've got to put it behind us, and I've got to put it behind myself for the next game."
