The unforgiving attention that has fallen upon one global Liverpool great shifted to another on Anfield's latest frustrating night.
The Egyptian forward has come under fire for his poor form this season - and was placed on the sidelines for the second successive Premier League game as Sunderland arrived on Wednesday.
But it was skipper Virgil van Dijk, a peerless defensive bedrock as Liverpool have swept up the complete set of major prizes, whose poor form became the focus during the draw.
Van Dijk, 34, and Salah, 33, both agreed to high-value two-year deals in the summer, with scarcely a Liverpool question asked at the idea of handing contracts to a seasoned pair much approaching the end of their careers than the start.
Truly, it was a reason for joy - but now there is no avoiding the brutal reality that standards have dropped alarmingly for both.
Liverpool have been exposed in defence ever since head coach Arne Slot and the club's transfer committee undertook a £450m summer rebuild that has not yet shown anything like value for money.
At the same time, Van Dijk has started to shed the air of invincibility he has carried since his £75m switch from Southampton in January 2018.
Van Dijk has faced additional challenges by center-back colleague Ibrahima Konate's dramatic dip, along with Milos Kerkez failing to settle at left-back. But the great Dutchman has also fought his own battles, as highlighted by his panic-stricken handball that gave away 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 deserved lead, Van Dijk surrendering the ball before standing off and turning his back on a 25-yard shot that deflected off him and drifted 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 finale, yes, but it was a situation Van Dijk courted with his uncharacteristic failure to act decisively, 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 erring and second-guessing himself."
As with Salah, a player of Van Dijk's caliber must not be written off after claiming two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a glittering Liverpool career.
He has, though, looked a pale imitation of his usual commanding presence this season, with the poest ball recovery rate per game during his Liverpool career, while defensive actions are also down on last season.
And, while leadership should not be Van Dijk's exclusive domain alone in a Liverpool team packed with experience, it was absent here. No-one was motivating a team that once again looked bewildered to grab the game by the throat.
Van Dijk's difficult night, which ended with him being used as the desperate measure of acting as an makeshift forward, was indicative of a horribly mediocre Liverpool performance - which made Sunday's win at West Ham seem like the outlier rather than the norm.
Slot kept faith with the side that ended a run of nine losses in 12 games at London Stadium, Salah once more observing from the sidelines.
The Egyptian was introduced at the start of the second half as the Kop turned to him for inspiration. It was not forthcoming, with £125m Alexander Isak also ineffective after scoring his first with his first league goal for Liverpool on Sunday.
Slot would have been under greater 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.
A late scare 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 dribbled past keeper Alisson.
Slot and his underperforming defending champions ultimately had to settle for a draw 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 slow, 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 crumbled.
But huge credit for the Reds' struggles on Wednesday must be given to Sunderland, who are being rewarded for a summer of notable ambition in the transfer market, coupled with the superb management of Regis le Bris.
The Black Cats were proactive, self-believing 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 frustrated they left Anfield without adding two more to their tally.
For Slot and Liverpool, it is time for reflection.
