Aston Villa boss Martin O'Neill described Liverpool as "exceptional" after their 5-0 defeat at Anfield.
"We were well beaten by an exceptional Liverpool side," he said.
"But we did contribute to our own downfall. At 1-0 down, we gave away an unbelievably bad goal. It was a shocking mistake.
"Liverpool have had two remarkable results before this game, beating Real Madrid and Manchester United - and they certainly did not need any help from us to achieve what they wanted.
"We played poorly. We gave away some lousy goals and we have to get back on track.
"We were doing fine four or five weeks ago, but we were well beaten by a better side. But we are a better side than we showed in this game."
