The intense attention that has fallen upon one global Liverpool legend switched to another on Anfield's fresh desperate night.
Mohamed Salah has faced examination for his poor form this season - and was relegated to the substitutes' bench for the second straight Premier League game as Sunderland visited on Wednesday.
But it was leader Virgil van Dijk, a peerless defensive foundation as Liverpool have secured the full collection of major trophies, whose poor form came under the microscope during the 1-1 draw.
Van Dijk, 34, and Salah, 33, both inked new lucrative two-year deals in the summer, with scarcely a Liverpool concern voiced at the idea of securing the futures to a veteran duo much closer to the end of their careers than the start.
Indeed, it was a cause of celebration - but now there is no denying the stark fact that standards have dropped worryingly for both.
Liverpool have been exposed in defence ever since head coach Arne Slot and the club's scouting department undertook a £450m summer overhaul that has not yet shown anything like its worth.
At the same time, Van Dijk has started to shed the air of invincibility he has possessed since his £75m move from Southampton in January 2018.
Van Dijk has received little support by defensive partner Ibrahima Konate's collapse in form, along with Milos Kerkez not finding his feet at left-back. But the esteemed defender has also struggled badly, as highlighted by his desperate handball that resulted in a penalty in the significant Champions League loss to PSV Eindhoven at Anfield.
It was exemplified in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a deserved lead, Van Dijk losing possession before backing away and averting his body on a 25-yard shot that hit him and drifted out of the reach of goalkeeper Alisson.
For a defender of such undoubted greatness, Van Dijk has an unusual habit of shying away on the ball, sometimes to Liverpool's cost.
Misfortune at the conclusion, yes, but it was a situation Van Dijk courted with his uncharacteristic failure to act decisively, Sunderland's Talbi taking advantage.
"Van Dijk surrenders possession and then he just backs off. It's the mistake. He needs to go to the ball. Him not making the decision means that no one else knows what to do."
"Virgil Van Dijk last season couldn't make a mistake. Every game he was imperious, but right now he's slipping up and hesitating."
As with Salah, a player of Van Dijk's stature must not be dismissed after securing two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a glittering Liverpool career.
He has, though, looked a shadow of his usual commanding presence this season, with the poest ball recovery rate per game during his Liverpool career, while defensive actions are also down on last season.
And, while leadership should not be Van Dijk's sole responsibility alone in a Liverpool team full of experience, it was absent here. No-one was rousing a team that once again looked bewildered to grab the game by the throat.
Van Dijk's poor display, which ended with him being used as the last resort of acting as an makeshift forward, was representative of a distinctly poor Liverpool performance - which made Sunday's win at West Ham seem like the outlier rather than the norm.
Slot stayed with the side that stopped a run of nine losses in 12 games at London Stadium, Salah once more observing from the sidelines.
The Egyptian was introduced at the start of the second half as the Kop looked to him for inspiration. It never came, with £125m Alexander Isak also anonymous after scoring his first with his first league goal for Liverpool on Sunday.
Slot would have been under greater pressure had Florian Wirtz's 81st-minute shot not taken a deflection off Nordi Mukiele to set up what Liverpool hoped would be a dramatic ending.
A late scare came - but at the other end. Liverpool were only saved from humiliation in stoppage time when Federico Chiesa's outstanding recovery run allowed him to turn Sunderland substitute Wilson Isidor's shot off the line after he had beaten keeper Alisson.
Slot and his underperforming defending champions ultimately had to settle for a draw knowing it could have been worse, with Alisson fortunate to turn Trai Hume's shot onto the bar in the first half before Omar Alderete headed against the post after the interval.
Liverpool were lethargic, ponderous and devoid of creativity. Even the typical final push after the equaliser carried minimal threat. Showings like this are the reason their title defence has collapsed.
But huge credit for the Reds' struggles on Wednesday must be given to Sunderland, who are being seeing the results for a summer of serious ambition in the transfer market, coupled with the excellent coaching of Regis le Bris.
The Black Cats were adventurous, assured and dangerous.
Sunderland are now sixth in the Premier League with 23 points. It is symptomatic of the manner in which they have grown into life in the Premier League that they will be frustrated they left Anfield without adding two more to their tally.
For Slot and Liverpool, it is a case of going back to basics.
