The unforgiving spotlight that has fallen upon one elite Liverpool legend switched to another on Anfield's latest disappointing night.
Mohamed Salah has been under scrutiny for his poor form this campaign - and was placed on the sidelines for the second successive Premier League game as Sunderland arrived on Wednesday.
But it was skipper Virgil van Dijk, a peerless defensive bedrock as Liverpool have secured the full collection of major prizes, whose struggles became the focus during the stalemate.
Van Dijk, 34, and Salah, 33, both inked lucrative new two-year deals in the summer, with not one Liverpool concern voiced at the prospect of handing contracts to a experienced stars much approaching the end of their careers than the start.
Truly, it was a cause of celebration - but now there is no denying the harsh truth that standards have dropped alarmingly for both.
Liverpool have been susceptible in defence ever since head coach Arne Slot and the club's transfer committee undertook a £450m summer refit that has not yet shown anything like its worth.
Concurrently, Van Dijk has started to shed the aura of invulnerability he has held since his £75m transfer from Southampton in January 2018.
Van Dijk has received little support by defensive partner Ibrahima Konate's dramatic dip, along with Milos Kerkez failing to settle at left-back. But the great Dutchman has also had significant difficulties, as demonstrated by his rash 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 losing possession before backing away and turning his back on a 25-yard shot that struck him and drifted out of the reach of goalkeeper Alisson.
For a defender of such undoubted greatness, Van Dijk has an curious trait of turning his back on the ball, sometimes to Liverpool's cost.
Bad luck at the finale, yes, but it was a situation Van Dijk provoked with his atypical failure to act decisively, Sunderland's Talbi taking advantage.
"Van Dijk gives the ball away and then he just drops off. It's the incorrect choice. 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 making mistakes and second-guessing himself."
As with Salah, a player of Van Dijk's stature must not be discarded after winning 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 worst recoveries 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 exclusive domain alone in a Liverpool team brimming with experience, it was lacking here. No-one was inspiring a team that once again looked lost to grab the game by the scruff of the neck.
Van Dijk's difficult night, which ended with him being used as the last resort of acting as an emergency striker, was indicative of a horribly mediocre Liverpool performance - which made Sunday's win at West Ham seem like the anomaly rather than the norm.
Slot stayed with the side that ended a run of nine losses in 12 games at London Stadium, Salah once more watching from the sidelines.
The Egyptian was introduced at the start of the second half as the Kop pinned hopes on him for inspiration. It was not forthcoming, with £125m Alexander Isak also quiet 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 taken a deflection off Nordi Mukiele to set up what Liverpool hoped would be a grandstand finish.
A late scare came - but at the other end. Liverpool were only avoided defeat 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 rounded keeper Alisson.
Slot and his underperforming defending champions ultimately had to accept the point knowing it could have been worse, with Alisson lucky 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 lacking in ideas. Even the customary late surge after the equaliser carried little conviction. Displays like this are the reason their title defence has crumbled.
But full acknowledgment for the Reds' struggles on Wednesday must be given to Sunderland, who are being rewarded for a summer of clear intent in the transfer market, coupled with the superb management of Regis le Bris.
The Black Cats were positive, confident and dangerous.
Sunderland are now sixth in the Premier League with 23 points. It is indicative of the manner in which they have embraced life in the Premier League that they will be unhappy they left Anfield without adding two more to their tally.
For Slot and Liverpool, it is back to the drawing board.
