The intense spotlight that has centered around one elite Liverpool icon switched to another on Anfield's fresh frustrating night.
Mohamed Salah has come under fire for his poor form this season - and was placed on the bench for the consecutive Premier League game as Sunderland visited on Wednesday.
But it was captain Virgil van Dijk, a peerless defensive rock as Liverpool have collected the array of major trophies, whose dip in performance became the focus during the 1-1 draw.
Van Dijk, 34, and Salah, 33, both signed new lucrative two-year deals in the summer, with scarcely a Liverpool question asked at the idea of securing the futures to a seasoned pair much closer to the end of their careers than the start.
Indeed, it was a cause of celebration - but now there is no avoiding the stark fact that standards have dropped alarmingly for both.
Liverpool have been susceptible in defence ever since head coach Arne Slot and the club's recruitment team embarked on a £450m summer rebuild that has still to demonstrate anything like its worth.
Concurrently, Van Dijk has started to lose the aura of invulnerability he has held since his £75m switch from Southampton in January 2018.
Van Dijk has not been helped by defensive partner Ibrahima Konate's loss of form, along with Milos Kerkez failing to settle at left-back. But the renowned star has also struggled badly, as highlighted by his rash handball that resulted in a penalty in the heavy 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 giving the ball away before retreating and turning his back on a 25-yard shot that deflected off him and floated out of the reach of goalkeeper Alisson.
For a defender of such proven caliber, Van Dijk has an peculiar tendency of turning his back on the ball, sometimes to Liverpool's disadvantage.
Bad luck at the finale, yes, but it was a situation Van Dijk provoked with his unusual failure to act decisively, Sunderland's Talbi capitalising.
"Van Dijk gives the ball away and then he just drops 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 faultless. Every game he was dominant, but right now he's slipping up and doubting himself."
As with Salah, a player of Van Dijk's pedigree must not be dismissed after securing two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a stellar 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 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 brimming with experience, it was lacking here. No-one was rousing a team that once again looked bewildered to take control by the scruff of the neck.
Van Dijk's poor display, which ended with him being used as the last resort of acting as an last-ditch attacker, was indicative of a distinctly poor Liverpool performance - which made Sunday's win at West Ham seem like the exception rather than the norm.
Slot persisted 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 came on at the start of the second half as the Kop pinned hopes on him for inspiration. It never came, with £125m Alexander Isak also anonymous after getting off the mark 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 dramatic ending.
Late drama came - but at the other end. Liverpool were only spared embarrassment in stoppage time when Federico Chiesa's outstanding recovery run allowed him to turn Sunderland substitute Wilson Isidor's shot off the line after he had beaten keeper Alisson.
Slot and his underperforming defending champions ultimately had to take a 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 slow, unimaginative and short on invention. Even the typical final push after the equaliser carried scant belief. Performances 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 seeing the results for a summer of clear intent in the transfer market, coupled with the superb management of Regis le Bris.
The Black Cats were positive, assured and threatening.
Sunderland are now sixth in the Premier League with 23 points. It is telling 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.
