The intense attention that has been trained on one world-class Liverpool legend switched to another on Anfield's fresh desperate night.
Mohamed Salah has come under fire for his subpar performances this campaign - and was placed on the bench for the second straight Premier League game as Sunderland arrived on Wednesday.
But it was leader Virgil van Dijk, a exceptional defensive foundation as Liverpool have swept up the complete set of major prizes, whose poor form took center stage during the 1-1 draw.
Van Dijk, 34, and Salah, 33, both inked lucrative new two-year deals in the summer, with barely a Liverpool concern voiced at the prospect of securing the futures to a veteran duo much nearer to the end of their careers than the start.
In fact, it was a moment of optimism - but now there is no denying the stark fact that levels have fallen alarmingly for both.
Liverpool have been susceptible in defence ever since head coach Arne Slot and the club's scouting department undertook a £450m summer rebuild that has not yet shown anything like value for money.
At the same time, Van Dijk has started to forfeit the air of invincibility he has held since his £75m move from Southampton in January 2018.
Van Dijk has faced additional challenges by center-back colleague 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 demonstrated by his desperate handball that gave away 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 losing possession before retreating and averting his body on a 25-yard shot that hit him and looped out of the reach of goalkeeper Alisson.
For a defender of such unquestionable quality, Van Dijk has an peculiar tendency of turning away on the ball, sometimes to Liverpool's cost.
Bad luck at the conclusion, yes, but it was a situation Van Dijk provoked with his atypical failure to act decisively, Sunderland's Talbi seizing the moment.
"Van Dijk gives the ball away 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 was impeccable. Every game he was dominant, but right now he's slipping up and hesitating."
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 glittering Liverpool career.
He has, though, looked a shadow of his usual imperious self this season, with the lowest recovery numbers 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 sole responsibility alone in a Liverpool team packed with experience, it was missing here. No-one was rousing a team that once again looked clueless to grab the game by the initiative.
Van Dijk's difficult night, which ended with him being used as the emergency option of acting as an emergency striker, was indicative of a deeply underwhelming Liverpool performance - which made Sunday's win at West Ham seem like the exception rather than the rule.
Slot persisted with the side that stopped 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 turned to him for inspiration. It never came, with £125m Alexander Isak also quiet after scoring his first 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 taken a deflection off Nordi Mukiele to set up what Liverpool hoped would be a dramatic ending.
A late scare 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 beaten keeper Alisson.
Slot and his fading champions ultimately had to accept the point 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 lethargic, ponderous and short on invention. Even the traditional late rally after the equaliser carried scant belief. Showings like this are the reason their defense of their crown has collapsed.
But huge credit for the Reds' struggles on Wednesday must be given to Sunderland, who are being reaping the benefits for a summer of notable ambition in the transfer market, coupled with the superb management of Regis le Bris.
The Black Cats were proactive, self-believing and a genuine threat.
Sunderland are now sixth in the Premier League with 23 points. It is telling of the manner in which they have embraced 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 back to the drawing board.
