The intense attention that has been trained on one world-class Liverpool great shifted to another on Anfield's most recent desperate night.
The Egyptian forward has been under scrutiny for his poor form this campaign - and was relegated to the sidelines for the second successive Premier League game as Sunderland arrived on Wednesday.
But it was leader Virgil van Dijk, a exceptional defensive rock as Liverpool have secured the complete set of major prizes, whose struggles became the focus during the stalemate.
Van Dijk, 34, and Salah, 33, both inked new lucrative two-year deals in the summer, with not one Liverpool eyebrow raised at the idea of securing the futures to a seasoned pair 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 levels have fallen alarmingly for both.
Liverpool have been exposed in defence ever since boss Arne Slot and the club's recruitment team undertook a £450m summer refit that has still to demonstrate anything like a good return.
At the same time, Van Dijk has started to lose the air of invincibility he has held since his £75m move from Southampton in January 2018.
Van Dijk has faced additional challenges by fellow defender Ibrahima Konate's loss of form, along with Milos Kerkez struggling to adapt at left-back. But the renowned star has also had significant difficulties, as proved by his rash handball that conceded a penalty in the heavy Champions League loss to PSV Eindhoven at Anfield.
It was exemplified in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a merited lead, Van Dijk losing possession before backing away and turning his back on a 25-yard shot that hit him and looped out of the reach of goalkeeper Alisson.
For a defender of such undoubted greatness, Van Dijk has an peculiar tendency of shying 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 act decisively, Sunderland's Talbi capitalising.
"Van Dijk surrenders possession and then he just drops 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 commanding, but right now he's making mistakes and second-guessing himself."
As with Salah, a player of Van Dijk's stature must not be dismissed after claiming 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 commanding presence 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 brimming with experience, it was missing here. No-one was rousing 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 last-ditch attacker, was representative of a distinctly poor Liverpool performance - which made Sunday's win at West Ham seem like the exception 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 observing from the sidelines.
The Egyptian emerged 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 opening his account with his first league goal for Liverpool on Sunday.
Slot would have been under increased scrutiny had Florian Wirtz's 81st-minute shot not taken a deflection off Nordi Mukiele to set up what Liverpool hoped would be a dramatic ending.
Stoppage-time tension came - but at the other end. Liverpool were only avoided defeat in stoppage time when Federico Chiesa's outstanding recovery run allowed him to turn Sunderland substitute Wilson Isidor's shot off the line after he had beaten keeper Alisson.
Slot and his fading 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 typical final push after the equaliser carried scant belief. Showings like this are the reason their defense of their crown has collapsed.
But huge credit 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 fine work of Regis le Bris.
The Black Cats were proactive, assured and dangerous.
Sunderland are now sixth in the Premier League with 23 points. It is telling of the manner in which they have adapted to life in the Premier League that they will be unhappy they left Anfield without adding two more to their tally.
For Slot and Liverpool, it is time for reflection.
