The unforgiving attention that has fallen upon one world-class Liverpool icon shifted to another on Anfield's fresh desperate night.
Mohamed Salah has faced examination for his struggles this campaign - and was relegated to the bench for the consecutive Premier League game as the Black Cats came to town on Wednesday.
But it was leader Virgil van Dijk, a exceptional defensive foundation as Liverpool have swept up the full collection of major prizes, whose struggles took center stage during the 1-1 draw.
Van Dijk, 34, and Salah, 33, both signed lucrative new two-year deals in the summer, with barely a Liverpool question asked at the idea of handing contracts to a experienced stars much approaching the end of their careers than the start.
Truly, it was a moment of optimism - but now there is no denying the brutal reality that performance has dipped concerningly for both.
Liverpool have been susceptible in defence ever since head coach Arne Slot and the club's recruitment team began a £450m summer refit that has yet to prove anything like its worth.
Concurrently, Van Dijk has started to shed the aura of invulnerability he has held since his £75m move from Southampton in January 2018.
Van Dijk has not been helped by defensive partner Ibrahima Konate's collapse in form, along with Milos Kerkez failing to settle at left-back. But the renowned star has also struggled badly, as proved by his rash 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 surrendering the ball before standing off and averting his body on a 25-yard shot that deflected off him and drifted out of the reach of goalkeeper Alisson.
For a defender of such unquestionable quality, Van Dijk has an unusual habit of turning his back on the ball, sometimes to Liverpool's disadvantage.
Ill fortune at the end, yes, but it was a situation Van Dijk invited with his uncharacteristic failure to take charge, Sunderland's Talbi seizing the moment.
"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 was impeccable. Every game he was imperious, but right now he's making mistakes and doubting himself."
As with Salah, a player of Van Dijk's caliber must not be discarded after securing two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a illustrious Liverpool career.
He has, though, looked a shadow of his usual dominant persona this season, with the poest ball recovery rate per game during his Liverpool career, while key defensive stats 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 missing here. No-one was inspiring 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 desperate measure of acting as an last-ditch attacker, was symptomatic of a distinctly poor Liverpool performance - which made Sunday's win at West Ham seem like the exception rather than the standard.
Slot persisted with the side that halted a run of nine losses in 12 games at London Stadium, Salah once more starting on the sidelines.
The Egyptian came on at the start of the second half as the Kop pinned hopes on him for inspiration. It failed to materialize, with £125m Alexander Isak also ineffective after opening his account with his first league goal for Liverpool on Sunday.
Slot would have been under increased scrutiny had Florian Wirtz's 81st-minute shot not deflected in off Nordi Mukiele to set up what Liverpool hoped would be a thrilling finale.
A late scare came - but at the other end. Liverpool were only saved from humiliation in stoppage time when Federico Chiesa's superb tracking back 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 devoid of creativity. Even the typical final push after the equaliser carried scant belief. Performances like this are the reason their defense of their crown has fallen apart.
But significant praise for the Reds' struggles on Wednesday must be given to Sunderland, who are being reaping the benefits for a summer of clear intent in the transfer market, coupled with the fine work of Regis le Bris.
The Black Cats were proactive, confident and threatening.
Sunderland are now sixth in the Premier League with 23 points. It is symptomatic of the manner in which they have adapted to 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 time for reflection.
