The unforgiving focus that has fallen upon one global Liverpool icon shifted to another on Anfield's latest frustrating night.
The Egyptian forward has come under fire 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 leader Virgil van Dijk, a unmatched defensive foundation as Liverpool have collected the array of major trophies, whose struggles came under the microscope during the stalemate.
Van Dijk, 34, and Salah, 33, both agreed to new lucrative two-year deals in the summer, with barely a Liverpool question asked at the notion of securing the futures to a experienced stars much nearer to the end of their careers than the start.
In fact, it was a moment of optimism - but now there is no escaping the stark fact that performance has dipped concerningly for both.
Liverpool have been exposed in defence ever since manager Arne Slot and the club's recruitment team began a £450m summer rebuild that has not yet shown anything like its worth.
Concurrently, Van Dijk has started to forfeit the aura of invulnerability he has possessed since his £75m switch from Southampton in January 2018.
Van Dijk has faced additional challenges by center-back colleague Ibrahima Konate's collapse in form, along with Milos Kerkez struggling to adapt at left-back. But the renowned star has also struggled badly, as proved by his rash handball that resulted in a penalty in the heavyweight Champions League loss to PSV Eindhoven at Anfield.
It was captured in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a deserved lead, Van Dijk giving the ball away before retreating and turning away on a 25-yard shot that deflected off him and floated out of the reach of goalkeeper Alisson.
For a defender of such unquestionable quality, Van Dijk has an curious trait of turning his back on the ball, sometimes to Liverpool's disadvantage.
Bad luck at the end, yes, but it was a situation Van Dijk courted with his uncharacteristic failure to make a decisive move, Sunderland's Talbi seizing the moment.
"Van Dijk surrenders possession and then he just drops 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 couldn't make a mistake. Every game he was dominant, but right now he's slipping up and hesitating."
As with Salah, a player of Van Dijk's stature must not be written off after claiming two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a stellar Liverpool career.
He has, though, looked a shadow of his usual imperious self 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 sole responsibility alone in a Liverpool team full of experience, it was absent here. No-one was inspiring a team that once again looked clueless to seize the initiative by the initiative.
Van Dijk's subpar showing, which ended with him being used as the desperate measure of acting as an last-ditch attacker, was indicative 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 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 looked to him for inspiration. It failed to materialize, with £125m Alexander Isak also quiet after opening his account with his first league goal for Liverpool on Sunday.
Slot would have been under increased scrutiny had Florian Wirtz's 81st-minute shot not taken a deflection off Nordi Mukiele to set up what Liverpool hoped would be a thrilling finale.
Late drama 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 take a 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 lethargic, ponderous and short on invention. Even the typical final push after the equaliser carried minimal threat. Performances 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 reaping the benefits for a summer of notable ambition in the transfer market, coupled with the fine work of Regis le Bris.
The Black Cats were positive, assured and dangerous.
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 a case of going back to basics.
