The unforgiving focus that has fallen upon one world-class Liverpool great turned to another on Anfield's fresh desperate night.
The Egyptian forward has been under scrutiny for his poor form this campaign - and was placed on the bench for the second successive Premier League game as Sunderland came to town on Wednesday.
But it was captain Virgil van Dijk, a unmatched defensive foundation as Liverpool have swept up the array of major trophies, whose struggles became the focus during the 1-1 draw.
Van Dijk, 34, and Salah, 33, both agreed to high-value two-year deals in the summer, with barely a Liverpool question asked at the notion of offering extensions to a veteran duo much approaching the end of their careers than the start.
Truly, it was a moment of optimism - but now there is no avoiding the stark fact that performance has dipped alarmingly for both.
Liverpool have been susceptible in defence ever since head coach Arne Slot and the club's recruitment team began a £450m summer rebuild that has yet to prove anything like a good return.
At the same time, Van Dijk has started to forfeit the air of invincibility he has held since his £75m transfer from Southampton in January 2018.
Van Dijk has faced additional challenges by fellow defender Ibrahima Konate's loss of form, along with Milos Kerkez not finding his feet at left-back. But the renowned star has also had significant difficulties, as highlighted by his panic-stricken handball that resulted in 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 losing possession before standing off 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 his back on the ball, sometimes to Liverpool's detriment.
Bad luck at the end, yes, but it was a situation Van Dijk courted with his atypical failure to make a decisive move, Sunderland's Talbi taking advantage.
"Van Dijk surrenders possession 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 couldn't make a mistake. Every game he was imperious, but right now he's slipping up and hesitating."
As with Salah, a player of Van Dijk's pedigree must not be dismissed after winning two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a stellar Liverpool career.
He has, though, looked a faded version of his usual dominant persona this season, with the lowest recovery numbers per game during his Liverpool career, while key defensive stats are also down on last season.
And, while leadership should not be Van Dijk's preserve alone in a Liverpool team packed with experience, it was missing here. No-one was inspiring a team that once again looked lost to seize the initiative by the throat.
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 deeply underwhelming Liverpool performance - which made Sunday's win at West Ham seem like the anomaly rather than the rule.
Slot stayed 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 emerged at the start of the second half as the Kop looked to him for inspiration. It was not forthcoming, with £125m Alexander Isak also anonymous after opening his account with his first league goal for Liverpool on Sunday.
Slot would have been under greater 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.
A late scare came - but at the other end. Liverpool were only avoided defeat 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 fading champions ultimately had to accept the point knowing it could have been worse, with Alisson fortunate 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 devoid of creativity. Even the typical final push after the equaliser carried scant belief. Performances like this are the reason their attempt to retain the title has crumbled.
But full acknowledgment 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, assured and threatening.
Sunderland are now sixth in the Premier League with 23 points. It is symptomatic of the manner in which they have grown into 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 time for reflection.
