Jurgen Klopp brought up Roy Keane in his post-match assessment of Liverpool's shocking thrashing from Aston Villa.
The Premier League champions were utterly demolished by the Villans in a 7-2 result.
It started off horrifically for the Reds when Adrian, standing in for the injured Alisson, gave the ball away after five minutes that saw Ollie Watkins score his first Premier League goal.
He doubled his tally after 20 minutes before Mohamed Salah got one back, only for John McGinn to restore the home side's two-goal lead.
Moments later, Watkins scored a header - completing a perfect hat-trick - before half-time.
Liverpool were expected to bounce back after the break but Ross Barkley scored before Jack Grealish grabbed two, while Salah netted another, to make it 7-2.
It follows on from a tense exchange of words between Klopp and Keane when the Liverpool boss took offence to the Sky Sports pundit's remarks about their defending against Arsenal.
Keane said they played 'sloppy' at the back and Klopp bit back, but on Sunday night he made an admission.
He said: "Last week, Mr. Keane said we defended sloppy - tonight it was not sloppy, it was just bad.
"I have to admit that, I cannot change that now. I would love a training session tomorrow.
"I hope they all come back healthy and use the two days between return and the derby.
" Everton are in a good moment and a proper team."
Liverpool's mammoth loss has been downplayed by Klopp, who has insisted that the match was a one-off.
He added: "For different reasons Aston Villa, who did really well tonight, forced all the mistakes that we made.
"We played into their hands with the first goal and with the second, and the third. Then the game has a specific direction.
"For me, we put all our rubbish things in one game. Fine, we can start again. I cannot change that now.
"I am 53 and have saw everything in football but it doesn't mean I have a solution for everything.
"Villa did really well but we did so bad. We can defend so much better than tonight. We lost it in the wrong moments. It is difficult and that means we cannot score."
