The glaring focus that has centered around one global Liverpool legend turned to another on Anfield's latest frustrating night.
The Egyptian forward has been under scrutiny for his subpar performances this campaign - and was placed on the sidelines for the second successive Premier League game as Sunderland arrived on Wednesday.
But it was leader Virgil van Dijk, a peerless defensive rock as Liverpool have secured the full collection of major trophies, whose poor form came under the microscope during the draw.
Van Dijk, 34, and Salah, 33, both signed lucrative new two-year deals in the summer, with not one Liverpool question asked at the idea of offering extensions to a experienced stars much approaching the end of their careers than the start.
In fact, it was a reason for joy - but now there is no escaping the harsh truth that standards have dropped alarmingly for both.
Liverpool have been exposed in defence ever since head coach Arne Slot and the club's scouting department embarked on a £450m summer rebuild that has not yet shown anything like a good return.
Simultaneously, Van Dijk has started to shed the sense of being untouchable he has held since his £75m switch 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 not finding his feet at left-back. But the renowned star has also had significant difficulties, as demonstrated by his rash handball that gave away a penalty in the significant 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 struck him and drifted out of the reach of goalkeeper Alisson.
For a defender of such undoubted greatness, Van Dijk has an unusual habit of turning his back on the ball, sometimes to Liverpool's detriment.
Misfortune at the finale, yes, but it was a situation Van Dijk courted with his atypical failure to make a decisive move, Sunderland's Talbi seizing the moment.
"Van Dijk loses the ball and then he just retreats. 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 dominant, but right now he's slipping up and second-guessing himself."
As with Salah, a player of Van Dijk's caliber must not be written off after securing two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a glittering Liverpool career.
He has, though, looked a shadow of his usual dominant persona this season, with the poest ball recovery rate 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 motivating a team that once again looked lost to grab the game by the throat.
Van Dijk's difficult night, which ended with him being used as the last resort of acting as an last-ditch attacker, was representative of a distinctly poor Liverpool performance - which made Sunday's win at West Ham seem like the outlier rather than the standard.
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 emerged at the start of the second half as the Kop turned to him for inspiration. It never came, with £125m Alexander Isak also quiet 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 taken a deflection off Nordi Mukiele to set up what Liverpool hoped would be a thrilling finale.
Stoppage-time tension came - but at the other end. Liverpool were only saved from humiliation 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 rounded keeper Alisson.
Slot and his underperforming defending champions ultimately had to take a 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, unimaginative and devoid of creativity. Even the traditional late rally after the equaliser carried little conviction. Showings like this are the reason their attempt to retain the title has fallen apart.
But significant praise 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 fine work of Regis le Bris.
The Black Cats were proactive, 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 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 time for reflection.
