The unforgiving focus that has fallen upon one global Liverpool legend turned to another on Anfield's latest frustrating night.
The Egyptian forward has been under scrutiny for his poor form this campaign - and was placed on the bench for the consecutive Premier League game as Sunderland came to town on Wednesday.
But it was skipper Virgil van Dijk, a exceptional defensive bedrock as Liverpool have collected the complete set of major prizes, whose poor form took center stage during the draw.
Van Dijk, 34, and Salah, 33, both signed new lucrative two-year deals in the summer, with not one Liverpool question asked at the notion of securing the futures to a veteran duo much closer to 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 levels have fallen alarmingly for both.
Liverpool have been vulnerable in defence ever since boss Arne Slot and the club's transfer committee began a £450m summer overhaul that has yet to prove anything like value for money.
Concurrently, Van Dijk has started to shed the air of invincibility he has carried since his £75m move from Southampton in January 2018.
Van Dijk has received little support by center-back colleague Ibrahima Konate's dramatic dip, along with Milos Kerkez failing to settle at left-back. But the renowned star has also struggled badly, as proved by his panic-stricken handball that conceded a penalty in the significant Champions League loss to PSV Eindhoven at Anfield.
It was encapsulated in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a well-earned lead, Van Dijk giving the ball away before backing away and averting his body on a 25-yard shot that struck him and drifted out of the reach of goalkeeper Alisson.
For a defender of such proven caliber, Van Dijk has an curious trait of turning his back on the ball, sometimes to Liverpool's disadvantage.
Misfortune at the conclusion, yes, but it was a situation Van Dijk provoked with his uncharacteristic failure to take charge, Sunderland's Talbi seizing the moment.
"Van Dijk surrenders possession and then he just backs off. It's the incorrect choice. 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 stature must not be discarded after securing 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 dominant persona this season, with the worst recoveries 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 exclusive domain alone in a Liverpool team full of experience, it was lacking here. No-one was inspiring a team that once again looked bewildered to seize the initiative by the scruff of the neck.
Van Dijk's subpar showing, which ended with him being used as the desperate measure of acting as an makeshift forward, 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 stayed 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 was introduced at the start of the second half as the Kop looked to 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.
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 beaten keeper Alisson.
Slot and his fading 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 lethargic, labored and short on invention. Even the traditional late rally after the equaliser carried little conviction. Displays like this are the reason their title defence has crumbled.
But full acknowledgment for the Reds' struggles on Wednesday must be given to Sunderland, who are being rewarded for a summer of clear intent in the transfer market, coupled with the fine work of Regis le Bris.
The Black Cats were adventurous, self-believing and dangerous.
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 unhappy they left Anfield without adding two more to their tally.
For Slot and Liverpool, it is a case of going back to basics.
