The intense spotlight that has fallen upon one elite Liverpool legend shifted to another on Anfield's most recent desperate night.
Mohamed Salah has come under fire for his struggles this campaign - and was relegated to the substitutes' bench for the second straight Premier League game as the Black Cats arrived on Wednesday.
But it was captain Virgil van Dijk, a peerless defensive bedrock as Liverpool have collected the array of major trophies, whose poor form came under the microscope during the draw.
Van Dijk, 34, and Salah, 33, both inked lucrative new two-year deals in the summer, with scarcely a Liverpool concern voiced at the idea of securing the futures to a seasoned pair much nearer to the end of their careers than the start.
Truly, it was a cause of celebration - but now there is no denying the stark fact that standards have dropped worryingly for both.
Liverpool have been susceptible in defence ever since boss Arne Slot and the club's scouting department embarked on a £450m summer rebuild that has yet to prove anything like value for money.
Simultaneously, Van Dijk has started to lose the sense of being untouchable he has carried since his £75m switch 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 not finding his feet at left-back. But the esteemed defender has also fought his own battles, as proved by his desperate handball that gave away a penalty in the significant Champions League loss to PSV Eindhoven at Anfield.
It was captured in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a merited 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 undoubted greatness, Van Dijk has an unusual habit of turning his back on the ball, sometimes to Liverpool's cost.
Ill fortune at the finale, yes, but it was a situation Van Dijk provoked with his uncharacteristic failure to make a decisive move, Sunderland's Talbi taking advantage.
"Van Dijk loses the ball and then he just retreats. 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 imperious, but right now he's slipping up and doubting 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 illustrious Liverpool career.
He has, though, looked a faded version of his usual commanding presence 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 preserve alone in a Liverpool team brimming with experience, it was missing here. No-one was rousing a team that once again looked lost to take control by the initiative.
Van Dijk's subpar showing, which ended with him being used as the desperate measure of acting as an last-ditch attacker, was symptomatic of a distinctly poor Liverpool performance - which made Sunday's win at West Ham seem like the exception rather than the norm.
Slot kept faith 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 turned to him for inspiration. It never came, with £125m Alexander Isak also ineffective 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 been turned 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 dribbled past keeper Alisson.
Slot and his underperforming defending 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, labored and lacking in ideas. Even the traditional late rally after the equaliser carried little conviction. Showings like this are the reason their defense of their crown has crumbled.
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 fine work of Regis le Bris.
The Black Cats were adventurous, assured and a genuine threat.
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.
