Liverpool can look back on a host of reasons why they didn't hold onto their lead at Bournemouth.
The Reds looked as if they were cruising to an easy victory, first going 2-0 up and then later restoring their advantage to 3-1.
As we all know, that's not how it ended, with Bournemouth scoring a trio of late goals to win the game.
In truth, several Liverpool players were at fault, but one in particular has been singled out for some harsh criticism.
In the wake of their shock collapse, Jamie Carragher hit out at Loris Karius, insisting he has been unconvincing since his summer arrival.
"He [Karius] is yet to convince me in any game," Carragher said on Sky Sports, per the Mirror.
"It is still early days but he needs a massive improvement."
Of course, Carragher would dearly love for Karius to be a massive hit.
Neville typically blunt
It's safe to say the same can't be said of Gary Neville, who always love to revel in Liverpool's downfall at any given opportunity.
The former Manchester United full-back didn't mince his words when asked what he thought of the stopper, who has replaced Simon Mignolet as number one this season.
Skip to 13:30 to hear what he had to say on Karius:
"It's tough to win the league without a good goalkeeper, it is tough,' he said, quoted via the Daily Mail.
Not good enough
"He's not good enough that goalkeeper. You could see actually in his first game... was it against [Manchester] United on a Monday night? He looks nervous and he isn't good enough.
"Now he [Karius] might get better, he might get better but you watch Courtois yesterday [against Manchester City]... Courtois is good enough."
It doesn't make pleasant listening for Liverpool fans, who were hoping they were going to be rid of the kind of howlers Mignolet had become associated with.
Klopp has often compared his two goalkeepers and insisted they're at a similar level, but that might well be true for all the wrong reasons.
