The unforgiving focus that has been trained on one global Liverpool icon switched to another on Anfield's latest desperate night.
Mohamed Salah has come under fire for his poor form this season - and was relegated to the substitutes' bench for the consecutive Premier League game as Sunderland visited on Wednesday.
But it was skipper Virgil van Dijk, a unmatched defensive bedrock as Liverpool have swept up the full collection of major prizes, whose struggles became the focus during the 1-1 draw.
Van Dijk, 34, and Salah, 33, both agreed to high-value two-year deals in the summer, with not one Liverpool concern voiced at the idea of securing the futures to a veteran duo much nearer to the end of their careers than the start.
In fact, it was a reason for joy - but now there is no avoiding the stark fact that standards have dropped alarmingly for both.
Liverpool have been exposed in defence ever since head coach Arne Slot and the club's scouting department embarked on a £450m summer refit that has still to demonstrate anything like a good return.
Simultaneously, Van Dijk has started to shed the air of invincibility he has held since his £75m transfer from Southampton in January 2018.
Van Dijk has not been helped by center-back colleague Ibrahima Konate's collapse in form, along with Milos Kerkez struggling to adapt at left-back. But the great Dutchman has also had significant difficulties, as highlighted by his rash handball that conceded a penalty in the heavyweight Champions League loss to PSV Eindhoven at Anfield.
It was captured in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a well-earned lead, Van Dijk surrendering the ball before standing off and turning away 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 peculiar tendency of turning his back on the ball, sometimes to Liverpool's detriment.
Bad luck at the end, yes, but it was a situation Van Dijk courted with his uncharacteristic failure to act decisively, Sunderland's Talbi capitalising.
"Van Dijk gives the ball away and then he just backs 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 was faultless. Every game he was imperious, but right now he's erring and second-guessing himself."
As with Salah, a player of Van Dijk's stature must not be written off after winning two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a stellar Liverpool career.
He has, though, looked a pale imitation of his usual dominant persona this season, with the worst recoveries per game during his Liverpool career, while tackles and interceptions are also down on last season.
And, while leadership should not be Van Dijk's preserve alone in a Liverpool team brimming with experience, it was lacking here. No-one was rousing a team that once again looked bewildered to seize the initiative by the scruff of the neck.
Van Dijk's difficult night, which ended with him being used as the desperate measure 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 rule.
Slot stayed with the side that halted a run of nine losses in 12 games at London Stadium, Salah once more observing from the sidelines.
The Egyptian emerged at the start of the second half as the Kop pinned hopes on him for inspiration. It never came, 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 even more pressure had Florian Wirtz's 81st-minute shot not been turned in off Nordi Mukiele to set up what Liverpool hoped would be a grandstand finish.
Late drama came - but at the other end. Liverpool were only avoided defeat 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 rounded keeper Alisson.
Slot and his underperforming defending champions ultimately had to accept the 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 slow, unimaginative and devoid of creativity. Even the customary late surge after the equaliser carried minimal threat. Performances like this are the reason their title defence has crumbled.
But significant praise 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 excellent coaching of Regis le Bris.
The Black Cats were proactive, confident and dangerous.
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 unhappy they left Anfield without adding two more to their tally.
For Slot and Liverpool, it is a case of going back to basics.
