The glaring focus that has fallen upon one global Liverpool legend switched to another on Anfield's most recent desperate night.
The Egyptian forward has faced examination for his struggles this campaign - and was consigned to the substitutes' bench for the second straight Premier League game as the Black Cats came to town on Wednesday.
But it was skipper Virgil van Dijk, a exceptional defensive bedrock as Liverpool have collected the array of major prizes, whose struggles became the focus during the draw.
Van Dijk, 34, and Salah, 33, both inked high-value two-year deals in the summer, with barely a Liverpool concern voiced at the prospect of offering extensions to a experienced stars much closer to the end of their careers than the start.
Indeed, it was a moment of optimism - but now there is no escaping the stark fact that standards have dropped concerningly for both.
Liverpool have been vulnerable in defence ever since manager Arne Slot and the club's transfer committee embarked on a £450m summer overhaul that has yet to prove anything like value for money.
Simultaneously, Van Dijk has started to shed the air of invincibility he has possessed since his £75m transfer from Southampton in January 2018.
Van Dijk has received little support 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 had significant difficulties, as demonstrated by his panic-stricken handball that conceded 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 surrendering the ball before backing away and turning away on a 25-yard shot that hit him and looped out of the reach of goalkeeper Alisson.
For a defender of such proven caliber, Van Dijk has an curious trait of turning his back on the ball, sometimes to Liverpool's detriment.
Misfortune at the conclusion, yes, but it was a situation Van Dijk provoked with his atypical failure to take charge, Sunderland's Talbi taking advantage.
"Van Dijk loses the ball 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 couldn't make a mistake. Every game he was imperious, but right now he's slipping up and hesitating."
As with Salah, a player of Van Dijk's caliber must not be written off after winning two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a illustrious Liverpool career.
He has, though, looked a faded version 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 packed with experience, it was missing here. No-one was motivating a team that once again looked bewildered to take control by the scruff of the neck.
Van Dijk's subpar showing, which ended with him being used as the last resort 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 outlier rather than the standard.
Slot persisted with the side that stopped 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 anonymous 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 deflected 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 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 struggling title-holders ultimately had to accept the point 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 devoid of creativity. Even the customary late surge after the equaliser carried scant belief. Showings like this are the reason their attempt to retain the title has crumbled.
But full acknowledgment for the Reds' struggles on Wednesday must be given to Sunderland, who are being reaping the benefits for a summer of clear intent in the transfer market, coupled with the superb management 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 indicative of the manner in which they have grown into 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 back to the drawing board.
