The glaring focus that has centered around one elite Liverpool icon shifted to another on Anfield's most recent disappointing night.
The Egyptian forward has come under fire for his poor form this campaign - and was placed on the bench for the second straight Premier League game as the Black Cats visited on Wednesday.
But it was skipper Virgil van Dijk, a exceptional defensive rock as Liverpool have secured the full collection of top honors, whose dip in performance came under the microscope during the 1-1 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 notion of offering extensions to a experienced stars much closer to the end of their careers than the start.
Indeed, it was a cause of celebration - but now there is no escaping the brutal reality that performance has dipped worryingly for both.
Liverpool have been vulnerable in defence ever since manager Arne Slot and the club's scouting department began a £450m summer overhaul that has not yet shown anything like value for money.
At the same time, Van Dijk has started to lose the sense of being untouchable he has carried since his £75m transfer from Southampton in January 2018.
Van Dijk has not been helped by defensive partner Ibrahima Konate's loss of form, along with Milos Kerkez struggling to adapt at left-back. But the great Dutchman has also fought his own battles, as highlighted by his desperate handball that gave away a penalty in the heavyweight Champions League loss to PSV Eindhoven at Anfield.
It was encapsulated 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 undoubted greatness, Van Dijk has an unusual habit of shying away on the ball, sometimes to Liverpool's detriment.
Ill fortune at the conclusion, yes, but it was a situation Van Dijk invited with his unusual failure to make a decisive move, Sunderland's Talbi taking advantage.
"Van Dijk gives the ball away 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 erring and hesitating."
As with Salah, a player of Van Dijk's caliber must not be written off 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 faded version 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 full of experience, it was missing here. No-one was rousing a team that once again looked lost to seize the initiative by the scruff of the neck.
Van Dijk's poor display, which ended with him being used as the desperate measure of acting as an emergency striker, was symptomatic of a horribly mediocre Liverpool performance - which made Sunday's win at West Ham seem like the outlier rather than the standard.
Slot stayed with the side that ended a run of nine losses in 12 games at London Stadium, Salah once more watching from the sidelines.
The Egyptian emerged at the start of the second half as the Kop pinned hopes on him for inspiration. It never came, with £125m Alexander Isak also quiet 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 been turned 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 saved from humiliation 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 rounded keeper Alisson.
Slot and his underperforming defending champions 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, labored and lacking in ideas. Even the customary late surge after the equaliser carried little conviction. Displays like this are the reason their attempt to retain the title has collapsed.
But significant praise for the Reds' struggles on Wednesday must be given to Sunderland, who are being reaping the benefits for a summer of serious ambition in the transfer market, coupled with the fine work of Regis le Bris.
The Black Cats were proactive, confident 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 back to the drawing board.
