The unforgiving attention that has fallen upon one elite Liverpool great turned to another on Anfield's most recent desperate night.
The Egyptian forward has come under fire for his poor form this season - and was relegated to the sidelines for the second straight Premier League game as the Black Cats visited on Wednesday.
But it was leader Virgil van Dijk, a peerless defensive bedrock as Liverpool have swept up the full collection of major prizes, whose struggles became the focus during the draw.
Van Dijk, 34, and Salah, 33, both signed new lucrative two-year deals in the summer, with barely a Liverpool question asked at the prospect of handing contracts to a veteran duo much nearer to the end of their careers than the start.
Truly, it was a moment of optimism - but now there is no denying the stark fact that performance has dipped alarmingly for both.
Liverpool have been vulnerable in defence ever since head coach Arne Slot and the club's scouting department embarked on a £450m summer refit that has not yet shown anything like value for money.
At the same time, Van Dijk has started to forfeit the sense of being untouchable he has held since his £75m transfer from Southampton in January 2018.
Van Dijk has not been helped by center-back colleague Ibrahima Konate's loss of form, along with Milos Kerkez struggling to adapt at left-back. But the renowned star has also fought his own battles, as proved by his rash handball that resulted in 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 surrendering the ball before backing away 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 end, yes, but it was a situation Van Dijk provoked with his unusual failure to make a decisive move, Sunderland's Talbi taking advantage.
"Van Dijk loses the ball and then he just retreats. 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 impeccable. Every game he was imperious, but right now he's erring and doubting himself."
As with Salah, a player of Van Dijk's stature must not be written off after securing two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a illustrious Liverpool career.
He has, though, looked a shadow 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 preserve alone in a Liverpool team brimming with experience, it was lacking here. No-one was motivating a team that once again looked bewildered to take control by the initiative.
Van Dijk's subpar showing, which ended with him being used as the emergency option of acting as an makeshift forward, 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 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 turned to him for inspiration. It was not forthcoming, 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 deflected in off Nordi Mukiele to set up what Liverpool hoped would be a grandstand finish.
Stoppage-time tension came - but at the other end. Liverpool were only spared embarrassment 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 dribbled past keeper Alisson.
Slot and his fading champions ultimately had to settle for a draw 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 sluggish, unimaginative and lacking in ideas. Even the typical final push after the equaliser carried little conviction. Performances like this are the reason their title defence 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 excellent coaching of Regis le Bris.
The Black Cats were adventurous, confident and a genuine threat.
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.
