The unforgiving focus that has been trained on one elite Liverpool great shifted to another on Anfield's most recent disappointing night.
The Egyptian forward has been under scrutiny for his poor form this season - and was placed on the sidelines for the second straight Premier League game as Sunderland came to town on Wednesday.
But it was leader Virgil van Dijk, a unmatched defensive foundation as Liverpool have secured the array of top honors, whose dip in performance became the focus during the 1-1 draw.
Van Dijk, 34, and Salah, 33, both agreed to new lucrative two-year deals in the summer, with scarcely a Liverpool concern voiced at the notion of handing contracts to a seasoned pair much nearer to 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 performance has dipped worryingly for both.
Liverpool have been exposed in defence ever since boss Arne Slot and the club's scouting department undertook a £450m summer rebuild that has yet to prove anything like a good return.
At the same time, Van Dijk has started to forfeit the sense of being untouchable he has carried since his £75m switch from Southampton in January 2018.
Van Dijk has not been helped by defensive partner Ibrahima Konate's collapse in form, along with Milos Kerkez not finding his feet at left-back. But the esteemed defender has also fought his own battles, as demonstrated by his desperate handball that conceded a penalty in the heavyweight Champions League loss to PSV Eindhoven at Anfield.
It was encapsulated in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a merited lead, Van Dijk giving the ball away before backing away and averting his body on a 25-yard shot that struck him and looped out of the reach of goalkeeper Alisson.
For a defender of such undoubted greatness, Van Dijk has an unusual habit of turning away on the ball, sometimes to Liverpool's cost.
Misfortune at the conclusion, yes, but it was a situation Van Dijk invited with his unusual failure to take charge, Sunderland's Talbi taking advantage.
"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 commanding, but right now he's erring and second-guessing himself."
As with Salah, a player of Van Dijk's stature must not be dismissed after claiming 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 lowest recovery numbers 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 preserve alone in a Liverpool team brimming with experience, it was absent here. No-one was inspiring a team that once again looked lost to seize the initiative by the throat.
Van Dijk's subpar showing, which ended with him being used as the emergency option of acting as an makeshift forward, was representative of a distinctly poor Liverpool performance - which made Sunday's win at West Ham seem like the exception rather than the norm.
Slot persisted 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 pinned hopes on him for inspiration. It failed to materialize, with £125m Alexander Isak also anonymous after scoring his first 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 grandstand finish.
Late drama came - but at the other end. Liverpool were only avoided defeat 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 dribbled past keeper Alisson.
Slot and his fading 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 sluggish, ponderous and lacking in ideas. Even the typical final push after the equaliser carried minimal threat. Performances like this are the reason their attempt to retain the title has crumbled.
But significant praise 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 excellent coaching of Regis le Bris.
The Black Cats were adventurous, self-believing and threatening.
Sunderland are now sixth in the Premier League with 23 points. It is telling of the manner in which they have adapted to life in the Premier League that they will be disappointed they left Anfield without adding two more to their tally.
For Slot and Liverpool, it is time for reflection.
