The glaring spotlight that has centered around one elite Liverpool legend switched to another on Anfield's latest desperate night.
The Egyptian forward has come under fire for his struggles this campaign - and was consigned to the bench for the consecutive Premier League game as the Black Cats visited on Wednesday.
But it was leader Virgil van Dijk, a peerless defensive bedrock as Liverpool have collected the full collection of top honors, whose struggles became the focus during the draw.
Van Dijk, 34, and Salah, 33, both agreed to new lucrative two-year deals in the summer, with scarcely a Liverpool eyebrow raised 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 denying the brutal reality that performance has dipped worryingly for both.
Liverpool have been susceptible in defence ever since boss Arne Slot and the club's scouting department undertook a £450m summer overhaul that has not yet shown anything like its worth.
At the same time, Van Dijk has started to shed the sense of being untouchable he has held since his £75m transfer from Southampton in January 2018.
Van Dijk has received little support by center-back colleague Ibrahima Konate's loss of form, along with Milos Kerkez failing to settle at left-back. But the renowned star has also had significant difficulties, as proved by his desperate 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 well-earned lead, Van Dijk giving the ball away before standing off and turning his back on a 25-yard shot that deflected off him and drifted out of the reach of goalkeeper Alisson.
For a defender of such proven caliber, Van Dijk has an unusual habit of shying away on the ball, sometimes to Liverpool's detriment.
Ill fortune at the end, yes, but it was a situation Van Dijk invited with his uncharacteristic failure to make a decisive move, Sunderland's Talbi capitalising.
"Van Dijk loses the ball and then he just retreats. It's the wrong decision. 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 hesitating."
As with Salah, a player of Van Dijk's caliber must not be dismissed 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 pale imitation of his usual imperious self this season, with the lowest recovery numbers per game during his Liverpool career, while defensive actions are also down on last season.
And, while leadership should not be Van Dijk's sole responsibility alone in a Liverpool team brimming with experience, it was lacking here. No-one was rousing a team that once again looked clueless to take control by the scruff of the neck.
Van Dijk's poor display, which ended with him being used as the emergency option of acting as an last-ditch attacker, was indicative of a horribly mediocre Liverpool performance - which made Sunday's win at West Ham seem like the anomaly rather than the standard.
Slot kept faith 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 came on at the start of the second half as the Kop pinned hopes on 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 thrilling finale.
Late drama 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 underperforming defending champions ultimately had to accept the 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 lacking in ideas. Even the typical final push after the equaliser carried scant belief. Showings like this are the reason their defense of their crown has collapsed.
But significant praise 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 positive, assured and threatening.
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 a case of going back to basics.
