Liverpool boss Brendan Rodgers says the 3-1 home defeat to Crystal Palace was a disappointing result for his side.
The Reds failed to produce the magic on Steven Gerrard's last game at Anfield despite taking the lead through Adam Lallana.
And the Northern Irishman believes the defensive department should have done better when the visitors scored.
"In terms of the result and the performance, it was disappointing," Rodgers said.
"We started reasonably well and scored a fantastic goal with Adam, but we made poor defensive errors across the field today.
"That punished us at the end of the first half and in the second half. We didn't defend well enough; their attacking players caused us a problem and we didn't cope with that.
"Overall, the second half was a disappointing performance.
"For the first goal, the player should never get anywhere near that area of the field. They cleared a ball up the line and we didn't defend the moment well enough.
"I thought our decision-making defensively wasn't very good today. In fairness to him, he sticks the ball in - it was a wonderful free-kick.
"But we're disappointed with how he arrived there; we saw Puncheon score with a set-piece last week, he's very good in those moments.
"The second one was arguably offside, when he makes contact with the ball there are two players offside. I would look at it from a coaching perspective that before the ball is even played, we didn't defend well on that side of the field.
"The third one was clearly and disappointingly outside the box. So those two goals we were probably very unfortunate on, in terms of the second one and the penalty.
"But it doesn't take away that we could have been better in defensive moments in the game."
