Karius, whose Champions League final horror show contributed to defeat by Real Madrid in May, marked only his second appearance since Kiev with a mistake at Prenton Park.
The 25-year-old spilled a free-kick by Oliver Norburn into the path of Johnny Smith, who reduced Liverpool’s lead to 3-1 after goals from Rafael Camacho, Sheyi Ojo and Adam Lallana had given the visitors a 3-0 interval lead.
Supporters still hurting from Karius’ awful display in Kiev were in no mood on social media to ignore the debate around his worthiness to play for the club.

So Karius had a howler again last night i’m not surprised at all , i’m not on here to gloat every time he has a mare but it’s clear to anyone who knows football that he’s an accident waiting to happen.
He’s not as good as Migs or Ward but Klopp is stubborn cos he’s his signing.

I like Karius very much and I genuinely want him to become world class with us. Fair to him, he showed signs of it last season, but unfortunately he doesn’t seem to have the mental fortitude. Yesterday’s error should be the final nail in the coffin, buy a GK please @LFC.

Same old same old Karius. Pathetic.

I really wouldn’t mind never seeing Karius in goal for #LFC again.
He may have been #2 in Germany, but has played like #2 in England.

Nah enough is enough @LFC, karius doesnt deserve this abuse, get another goalkeeper immediately and send the boy on loan

@LFC can’t seriously go another season with Karius in goal, it’s literally embarrassing ????????

Karius has to leave. Just replace him @LFC . Getting sick and tired seeing how bad he really is. The mistake he did was in a pre season game which is so concerning to start with. If we really want to improve and win titles, everybody knows we need a clas GK.

Listen, credit where credit is due and also if the guy is a liability, then we need to say…… Karius is no where near good enough. His best game is just about good enough and his worst game will kill us. We just need a presence in goal who can concentrate for 90 mins

Another day, another Karius howler. It was not in front of the football-viewing world on this occasion, and in the rather more low-key setting of League Two club Tranmere in a pre-season friendly. But such is the reach of social media and modern fandom the reactions of the Liverpool faithful are a mixture of blazing anger and very dark humour. One has to search hard for anyone with anything halfway decent to say about the German goalkeeper, whose performance in Kiev in May ended all hope of the club returning to the top of European football. The spotlight is destined to be fierce whenever Karius plays this season, and the reactions are unlikely to be pleasant, either.
