Peter Crouch and Michael Owen accused Liverpool of giving in to nerves by leaving a three-goal lead against an "incredible" side of RB Salzburg in Anfield on Wednesday night.
Mohamed Salah scored a fourth goal at home to hit a roller coaster night in Champions League football.
But the former Reds strikers were impressed by the collapse of the European champions after reaching a 3-0 lead in 36 minutes.

"That was mental, absolutely mental," said Crouch at BT Sport.
& # 39; Liverpool were flying, playing one of the best attacking players I've ever seen this season, and in the second half, I don't even know where to start. 3-3, you just couldn't have seen it.
& # 39; And then Salah comes up with the winner, but an amazing match, a lot of fun, but for the wrong reasons really for Liverpool in the end.
& # 39; They got a little nervous, Liverpool, you have to say. Once the first goal came in, then the second.
& # 39; You saw Fabinho being so calm on the ball, he was going out of play, they weren't as intricate as they were in the first half, so it definitely affected them.
"Obviously, the fourth goal killed them and they controlled the game and got it, but it went hairy for a while."

Owen added, "I was worried about that, I must admit." I totally agree with Crouchy, I thought that when it was 3-1 and then 3-2, I thought there were two people who looked nervous.
& # 39; Joe Gomez looked nervous, certainly Fabinho looked very nervous – he made three mistakes within five minutes and one led to the goal as well.
"You think a team that was in the Champions League final last season would be very calm in the group stage, but they shook it off and Liverpool did well to secure that slip and return to the top."
But the pair had a few words of praise for Salzburg, who retreated from a three-goal deficit to draw 3-3 on 60 minutes with Hwang Hee-chan, Takumi Minamino and substitute Erling Haaland.
"They were amazing," purred Crouch. “I thought attacking wisely was the first real test, but they turned out very well.

& # 39; It was a great offensive performance on their part. Minamino was class, Hwang, some great solo performances. And Haaland got off the bench to seal what he thought was the draw, but Salah appeared in the end.
& # 39; They deserve credit so they had a real chance. Their heads could have fallen 3-0, but they continued with the threat of attack.
Salah and Sadio Mane, who opened the scoring after nine minutes against the old team, also praised the opponents.
"I think they had a good game and after scoring three goals it was difficult," said Salah. & # 39; It was tough in the second half, but we won and we're happy with it.
Mane added, “That was really good, honestly. After 3-0 and 3-3, it became a very difficult game. I think we deserve to win. You have to respect this game all the time.
"To be honest, I knew this team because I was there for 2 ½ years, they never give up and they push all the time."
Jurgen Klopp regretted the decision making on his side, but believes they will have learned the lesson of the game.
"You better learn the lesson of the game and rate it during the game, but you need to talk about it after the game," he said.

& # 39; The moment has completely changed and you could see that it was really hard for us to set foot in the game again. I'm not angry or anything, I found ourselves playing very well and then we made the wrong decision, obviously.
& # 39; In the break, we try to change, but timing is a really important thing. We did not succeed until the score sheet was finally equal. And then we have a very important and enjoyable goal.
& # 39; But the problem with this team is that they don't care about the outcome, but about the night. The mistake we made was that we lost control of the game.
