The glaring focus that has centered around one world-class Liverpool great turned to another on Anfield's latest desperate night.
The Egyptian forward has faced examination for his poor form this campaign - and was consigned to the sidelines 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 swept up the full collection of top honors, whose struggles took center stage during the draw.
Van Dijk, 34, and Salah, 33, both agreed to new lucrative two-year deals in the summer, with not one Liverpool concern voiced at the idea of offering extensions to a veteran duo much nearer to the end of their careers than the start.
In fact, it was a cause of celebration - but now there is no denying the brutal reality that performance has dipped concerningly for both.
Liverpool have been susceptible in defence ever since head coach Arne Slot and the club's scouting department undertook a £450m summer rebuild that has not yet shown anything like its worth.
At the same time, Van Dijk has started to forfeit the sense of being untouchable he has possessed since his £75m transfer from Southampton in January 2018.
Van Dijk has received little support by fellow defender Ibrahima Konate's dramatic dip, along with Milos Kerkez failing to settle at left-back. But the renowned star has also fought his own battles, as proved by his desperate handball that gave away a penalty in the heavyweight 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 his back on a 25-yard shot that deflected off him and floated out of the reach of goalkeeper Alisson.
For a defender of such unquestionable quality, 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 take charge, Sunderland's Talbi capitalising.
"Van Dijk gives the ball away 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 making mistakes and doubting himself."
As with Salah, a player of Van Dijk's caliber must not be dismissed 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 pale imitation of his usual dominant persona 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 preserve alone in a Liverpool team packed with experience, it was missing here. No-one was inspiring a team that once again looked clueless to grab the game 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 emergency striker, was representative of a horribly mediocre Liverpool performance - which made Sunday's win at West Ham seem like the anomaly rather than the rule.
Slot stayed 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 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 quiet after opening his account with his first league goal for Liverpool on Sunday.
Slot would have been under greater pressure had Florian Wirtz's 81st-minute shot not been turned in off Nordi Mukiele to set up what Liverpool hoped would be a dramatic ending.
A late scare came - but at the other end. Liverpool were only saved from humiliation 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 slow, labored and lacking in ideas. Even the traditional late rally after the equaliser carried little conviction. Performances like this are the reason their title defence has collapsed.
But huge credit for the Reds' struggles on Wednesday must be given to Sunderland, who are being rewarded for a summer of clear intent in the transfer market, coupled with the excellent coaching of Regis le Bris.
The Black Cats were positive, confident 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 disappointed they left Anfield without adding two more to their tally.
For Slot and Liverpool, it is time for reflection.
