The unforgiving spotlight that has been trained on one elite Liverpool legend switched to another on Anfield's latest frustrating night.
Mohamed Salah has been under scrutiny for his poor form this campaign - and was relegated to the bench for the second straight Premier League game as Sunderland visited on Wednesday.
But it was captain Virgil van Dijk, a exceptional defensive bedrock as Liverpool have secured the full collection of major prizes, whose dip in performance became the focus during the stalemate.
Van Dijk, 34, and Salah, 33, both signed lucrative new two-year deals in the summer, with not one Liverpool eyebrow raised at the idea of offering extensions to a veteran duo much approaching the end of their careers than the start.
Indeed, it was a moment of optimism - but now there is no avoiding the stark fact that standards have dropped alarmingly for both.
Liverpool have been vulnerable in defence ever since head coach Arne Slot and the club's transfer committee embarked on a £450m summer rebuild that has not yet shown anything like its worth.
Concurrently, Van Dijk has started to forfeit the sense of being untouchable he has possessed since his £75m transfer from Southampton in January 2018.
Van Dijk has received little support by fellow defender Ibrahima Konate's dramatic dip, along with Milos Kerkez struggling to adapt at left-back. But the renowned star has also fought his own battles, as highlighted by his panic-stricken handball that conceded a penalty in the heavyweight Champions League loss to PSV Eindhoven at Anfield.
It was encapsulated in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a deserved lead, Van Dijk surrendering the ball before standing off and turning his back on a 25-yard shot that hit him and drifted out of the reach of goalkeeper Alisson.
For a defender of such proven caliber, Van Dijk has an curious trait of turning his back on the ball, sometimes to Liverpool's cost.
Misfortune at the conclusion, yes, but it was a situation Van Dijk courted with his atypical failure to act decisively, Sunderland's Talbi taking advantage.
"Van Dijk gives the ball away and then he just backs off. It's the wrong decision. 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 was impeccable. Every game he was commanding, but right now he's making mistakes and hesitating."
As with Salah, a player of Van Dijk's caliber must not be dismissed after winning two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a glittering Liverpool career.
He has, though, looked a faded version of his usual dominant persona this season, with the worst recoveries 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 brimming with experience, it was absent here. No-one was rousing a team that once again looked clueless to take control by the initiative.
Van Dijk's poor display, which ended with him being used as the last resort of acting as an last-ditch attacker, was representative of a deeply underwhelming Liverpool performance - which made Sunday's win at West Ham seem like the exception rather than the norm.
Slot kept faith with the side that ended a run of nine losses in 12 games at London Stadium, Salah once more observing from the sidelines.
The Egyptian came on at the start of the second half as the Kop turned to him for inspiration. It was not forthcoming, with £125m Alexander Isak also ineffective after getting off the mark with his first league goal for Liverpool on Sunday.
Slot would have been under greater pressure had Florian Wirtz's 81st-minute shot not deflected in off Nordi Mukiele to set up what Liverpool hoped would be a thrilling finale.
Stoppage-time tension came - but at the other end. Liverpool were only spared embarrassment in stoppage time when Federico Chiesa's excellent defensive sprint allowed him to turn Sunderland substitute Wilson Isidor's shot off the line after he had dribbled past keeper Alisson.
Slot and his fading champions ultimately had to take a point 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, labored and short on invention. Even the customary late surge after the equaliser carried scant belief. Performances like this are the reason their attempt to retain the title 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 notable ambition in the transfer market, coupled with the fine work of Regis le Bris.
The Black Cats were proactive, assured and threatening.
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 disappointed they left Anfield without adding two more to their tally.
For Slot and Liverpool, it is time for reflection.
