Jurgen Klopp was forced to face a barrage of difficult questions after his frail defence capitulated yet again as Liverpool were humbled 4-1 at Wembley by a rampant Tottenham Hotspur.
The Reds were an absolute shambles at the back, with Klopp even resorting to hauling Dejan Lovren off after only 30 minutes after the Croatian registered one of his worst performances yet, and that is saying something.
However, despite his quite obvious failings, it is not the Croatian who will be doing the most soul-searching when he gets to bed tonight, but rather his goalkeeper, Simon Mignolet.
The Belgian stopper became the sole bearer of a thoroughly unenviable record after Harry Kane punished more abominable defending to score Spurs' fourth.
Mignolet flapped dreadfully at a Christian Eriksen delivery, missing it completely before Jan Vertonghen's blocked shot fell to the feet of the more clinical Harry Kane who fired home.
Mignolet, who has been preferred to the equally terrifying Loris Karius in the league this season, now holds the record for the most defensive errors leading to goals by any player in the Premier League since his Liverpool debut in 2013.
Kane, who finished the game with two goals and an assist barely had to break a sweat, rather waiting to pounce on any Liverpool howlers and they came with joyous regularity.
Jurgen Klopp could barely watch as his side fell apart. Despite having one of the best attacks in the land, Klopp's back-line is quite possibly the worst. The Red's have conceded 15 goals away from home this season in the league, more than any other side, bottom dwellers Crystal palace included.
"The whole game the whole result was all our fault - Tottenham was good, they needed to be good, but we made it much too easy for them," said the German manager in the aftermath of the galling defeat.
"Four mistakes from us, and then Dele doesn't even hit the ball 100%.
"It's not about confidence. It's just about being 100% spot on. It was a really average day for us today."
It seems Mignolet isn't the only one with sleepless nights ahead of him.
