The unforgiving focus that has fallen upon one global Liverpool great turned to another on Anfield's latest desperate night.
The Egyptian forward has faced examination for his struggles this campaign - and was consigned to the bench for the consecutive Premier League game as Sunderland visited on Wednesday.
But it was skipper Virgil van Dijk, a peerless defensive foundation as Liverpool have secured the full collection of major prizes, whose poor form came under the microscope during the draw.
Van Dijk, 34, and Salah, 33, both signed lucrative new two-year deals in the summer, with scarcely a Liverpool eyebrow raised at the notion of handing contracts to a seasoned pair much approaching the end of their careers than the start.
Truly, it was a moment of optimism - but now there is no avoiding the brutal reality that levels have fallen concerningly for both.
Liverpool have been vulnerable in defence ever since boss Arne Slot and the club's recruitment team began a £450m summer rebuild that has still to demonstrate anything like value for money.
Concurrently, Van Dijk has started to forfeit the air of invincibility he has possessed since his £75m move from Southampton in January 2018.
Van Dijk has faced additional challenges by center-back colleague Ibrahima Konate's dramatic dip, along with Milos Kerkez struggling to adapt at left-back. But the esteemed defender has also struggled badly, 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 exemplified in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a well-earned lead, Van Dijk surrendering the ball before standing off and turning away on a 25-yard shot that hit him and looped out of the reach of goalkeeper Alisson.
For a defender of such proven caliber, Van Dijk has an peculiar tendency of turning his back on the ball, sometimes to Liverpool's disadvantage.
Ill fortune at the end, yes, but it was a situation Van Dijk courted with his unusual failure to make a decisive move, Sunderland's Talbi taking advantage.
"Van Dijk loses the ball and then he just backs 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 was faultless. Every game he was commanding, but right now he's making mistakes and doubting himself."
As with Salah, a player of Van Dijk's stature must not be dismissed 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 pale imitation of his usual dominant persona this season, with the worst recoveries 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 packed with experience, it was missing here. No-one was motivating a team that once again looked clueless to grab the game by the scruff of the neck.
Van Dijk's difficult night, which ended with him being used as the last resort of acting as an makeshift forward, was symptomatic of a deeply underwhelming Liverpool performance - which made Sunday's win at West Ham seem like the outlier 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 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 anonymous 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 been turned in off Nordi Mukiele to set up what Liverpool hoped would be a thrilling finale.
Stoppage-time tension came - but at the other end. Liverpool were only saved from humiliation 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 beaten keeper Alisson.
Slot and his underperforming defending champions ultimately had to settle for a draw 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 sluggish, unimaginative and devoid of creativity. Even the traditional late rally after the equaliser carried scant belief. Showings like this are the reason their defense of their crown 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 clear intent in the transfer market, coupled with the fine work of Regis le Bris.
The Black Cats were adventurous, self-believing and a genuine threat.
Sunderland are now sixth in the Premier League with 23 points. It is telling of the manner in which they have embraced 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 time for reflection.
