The glaring spotlight that has fallen upon one global Liverpool great shifted to another on Anfield's most recent frustrating night.
The Egyptian forward has been under scrutiny for his subpar performances this season - and was relegated to the substitutes' bench for the second successive Premier League game as Sunderland arrived on Wednesday.
But it was captain Virgil van Dijk, a peerless defensive bedrock as Liverpool have collected the array of major trophies, whose poor form became the focus during the draw.
Van Dijk, 34, and Salah, 33, both inked high-value two-year deals in the summer, with scarcely a Liverpool question asked at the idea of securing the futures to a veteran duo much approaching the end of their careers than the start.
Indeed, it was a reason for joy - but now there is no escaping the stark fact that levels have fallen alarmingly for both.
Liverpool have been susceptible in defence ever since manager Arne Slot and the club's recruitment team undertook a £450m summer rebuild that has yet to prove anything like its worth.
At the same time, Van Dijk has started to lose the aura of invulnerability he has possessed since his £75m switch from Southampton in January 2018.
Van Dijk has not been helped by center-back colleague Ibrahima Konate's collapse in form, along with Milos Kerkez not finding his feet at left-back. But the esteemed defender has also had significant difficulties, as proved by his desperate handball that resulted in a penalty in the heavy Champions League loss to PSV Eindhoven at Anfield.
It was captured in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a well-earned lead, Van Dijk losing possession before retreating and averting his body on a 25-yard shot that hit him and floated out of the reach of goalkeeper Alisson.
For a defender of such proven caliber, Van Dijk has an curious trait of turning away on the ball, sometimes to Liverpool's cost.
Misfortune at the conclusion, yes, but it was a situation Van Dijk provoked with his uncharacteristic failure to act decisively, Sunderland's Talbi capitalising.
"Van Dijk surrenders possession and then he just backs off. It's the mistake. 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 commanding, but right now he's erring and second-guessing himself."
As with Salah, a player of Van Dijk's stature must not be discarded 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 shadow of his usual commanding presence this season, with the poest ball recovery rate 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 exclusive domain alone in a Liverpool team packed with experience, it was missing here. No-one was motivating 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 emergency option of acting as an last-ditch attacker, was symptomatic of a horribly mediocre Liverpool performance - which made Sunday's win at West Ham seem like the exception rather than the standard.
Slot kept faith with the side that ended 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 turned to him for inspiration. It failed to materialize, with £125m Alexander Isak also ineffective 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 taken a deflection off Nordi Mukiele to set up what Liverpool hoped would be a grandstand finish.
A late scare came - but at the other end. Liverpool were only avoided defeat in stoppage time when Federico Chiesa's excellent defensive sprint allowed him to turn Sunderland substitute Wilson Isidor's shot off the line after he had rounded keeper Alisson.
Slot and his struggling title-holders 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 sluggish, unimaginative and devoid of creativity. Even the traditional late rally after the equaliser carried little conviction. Displays like this are the reason their attempt to retain the title has fallen apart.
But significant praise for the Reds' struggles on Wednesday must be given to Sunderland, who are being reaping the benefits for a summer of serious ambition 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 embraced 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 back to the drawing board.
