The glaring attention that has centered around one elite Liverpool legend turned to another on Anfield's fresh desperate night.
Mohamed Salah has faced examination for his struggles this campaign - and was consigned to the substitutes' bench for the consecutive Premier League game as Sunderland came to town on Wednesday.
But it was leader Virgil van Dijk, a peerless defensive bedrock as Liverpool have swept up the full collection of top honors, whose struggles took center stage during the 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 offering extensions to a seasoned pair much closer to the end of their careers than the start.
In fact, it was a cause of celebration - but now there is no avoiding the stark fact that levels have fallen alarmingly for both.
Liverpool have been exposed in defence ever since manager Arne Slot and the club's scouting department undertook a £450m summer overhaul that has not yet shown anything like value for money.
Simultaneously, Van Dijk has started to forfeit the sense of being untouchable he has held since his £75m move from Southampton in January 2018.
Van Dijk has faced additional challenges by fellow defender Ibrahima Konate's loss of form, along with Milos Kerkez struggling to adapt at left-back. But the renowned star has also had significant difficulties, as demonstrated by his panic-stricken handball that resulted in a penalty in the heavy Champions League loss to PSV Eindhoven at Anfield.
It was exemplified in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a merited lead, Van Dijk surrendering the ball before backing away and turning his back on a 25-yard shot that struck him and floated 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 detriment.
Misfortune at the conclusion, yes, but it was a situation Van Dijk invited with his uncharacteristic failure to act decisively, Sunderland's Talbi taking advantage.
"Van Dijk loses the ball and then he just drops 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 couldn't make a mistake. Every game he was dominant, but right now he's making mistakes and second-guessing himself."
As with Salah, a player of Van Dijk's stature must not be written off 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 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 exclusive domain alone in a Liverpool team full of experience, it was missing here. No-one was inspiring a team that once again looked clueless to grab the game by the scruff of the neck.
Van Dijk's subpar showing, which ended with him being used as the emergency option of acting as an makeshift forward, was indicative of a distinctly poor Liverpool performance - which made Sunday's win at West Ham seem like the outlier rather than the norm.
Slot persisted with the side that stopped a run of nine losses in 12 games at London Stadium, Salah once more starting on the sidelines.
The Egyptian emerged 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 opening his account 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.
Stoppage-time tension 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 dribbled past keeper Alisson.
Slot and his fading champions ultimately had to settle for a draw knowing it could have been worse, with Alisson blessed 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, ponderous and short on invention. Even the customary late surge after the equaliser carried minimal threat. Performances like this are the reason their attempt to retain the title has crumbled.
But full acknowledgment for the Reds' struggles on Wednesday must be given to Sunderland, who are being rewarded for a summer of notable ambition in the transfer market, coupled with the superb management 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 indicative 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.
