The intense focus that has centered around one global Liverpool legend switched to another on Anfield's most recent disappointing night.
Mohamed Salah has come under fire for his poor form this season - and was placed on the bench for the second successive Premier League game as the Black Cats came to town on Wednesday.
But it was skipper Virgil van Dijk, a exceptional defensive foundation as Liverpool have swept up the full collection of major trophies, whose struggles became the focus during the draw.
Van Dijk, 34, and Salah, 33, both inked new lucrative two-year deals in the summer, with scarcely a Liverpool concern voiced at the prospect of offering extensions to a seasoned pair much nearer to the end of their careers than the start.
In fact, it was a cause of celebration - but now there is no avoiding the brutal reality that standards have dropped worryingly for both.
Liverpool have been susceptible in defence ever since boss Arne Slot and the club's scouting department began a £450m summer overhaul that has not yet shown anything like its worth.
At the same time, Van Dijk has started to lose the sense of being untouchable he has possessed since his £75m move from Southampton in January 2018.
Van Dijk has not been helped by fellow defender Ibrahima Konate's collapse in form, along with Milos Kerkez failing to settle at left-back. But the renowned star has also had significant difficulties, as highlighted by his rash handball that conceded 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 well-earned lead, Van Dijk losing possession before standing off and averting his body on a 25-yard shot that hit him and drifted out of the reach of goalkeeper Alisson.
For a defender of such proven caliber, Van Dijk has an unusual habit of turning away on the ball, sometimes to Liverpool's cost.
Ill fortune at the finale, yes, but it was a situation Van Dijk invited with his uncharacteristic failure to act decisively, Sunderland's Talbi seizing the moment.
"Van Dijk loses the ball and then he just retreats. 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 impeccable. 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 caliber must not be discarded after claiming two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a illustrious Liverpool career.
He has, though, looked a pale imitation of his usual imperious self this season, with the poest ball recovery rate per game during his Liverpool career, while defensive actions 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 absent here. No-one was inspiring a team that once again looked bewildered to grab the game by the throat.
Van Dijk's subpar showing, which ended with him being used as the desperate measure of acting as an emergency striker, was representative of a horribly mediocre 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 failed to materialize, with £125m Alexander Isak also ineffective 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 deflected in off Nordi Mukiele to set up what Liverpool hoped would be a dramatic ending.
Stoppage-time tension 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 beaten keeper Alisson.
Slot and his struggling title-holders 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 slow, unimaginative and devoid of creativity. Even the typical final push after the equaliser carried scant belief. Showings like this are the reason their attempt to retain the title has fallen apart.
But huge credit 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 adventurous, self-believing and threatening.
Sunderland are now sixth in the Premier League with 23 points. It is indicative of the manner in which they have adapted to life in the Premier League that they will be disappointed they left Anfield without adding two more to their tally.
For Slot and Liverpool, it is a case of going back to basics.
