Liverpool have only got themselves for the "awful" second-half capitulation that saw them lose a 3-0 Champions League lead at Sevilla and draw 3-3, Alberto Moreno has said.
Victory would have sealed a place in the round-of-16 with a game to spare, but Jurgen Klopp's side conceded an equaliser in stoppage time.
Moreno, returning to face the side he left to join Liverpool in 2014, told Onda Cero radio: "We threw away three points.
"We were already through to the next round, but it was not to be. We knew that even with a 3-0 advantage it was going to be complicated, and that was the case.
"We had spoken at half-time about how with a 3-0 lead we still had to be careful. More than that [Sevilla playing well], it was a case of how awful we were and how many mistakes we made at the back.
"They didn't stop attacking in the second half -- but we came out half asleep."
Fouls by Moreno resulted in the two Wissam Ben Yedder goals that brought the home side back into contention and the left-back added: "It's beautiful to return home, to know that your family and friends are in the stands and to play in front of your former fans.
"But I cannot be happy with the result and letting go of a 3-0 lead. It's difficult to play at the Sanchez Pizjuan, whether it's in La Liga or in Europe. Sevilla have a great team.
"We need to look at the mistakes we made and move on to our next game. This is football."
Sevilla president Jose Castro praised the home fans in a crowd of more than 40,000 for their part in the comeback.
He told the club's official website: "Great things happen when the players and the fans come together.
"I can only describe it as spectacular, to be fully behind the team with a 3-0 deficit until the side started to give reasons to believe it was possible.
"This point is worth so much more. We have played against a team that has four times our budget and we were of that level.
"Their fans say that Liverpool never walks alone but our supporters have proved that they never give up on a big night."
Tuesday's result kept Sevilla second in Group E, a point adrift of leaders Liverpool with one game remaining.
Liverpool host Spartak Moscow on Dec. 6, while Sevilla play at winless Maribor.
