A Diminished Presence of His Imperious Self - Van Dijk Battles Waning Influence
The intense focus that has fallen upon one global Liverpool icon turned to another on Anfield's latest disappointing night.
The Egyptian forward has faced examination for his struggles this campaign - and was relegated to the sidelines for the second successive Premier League game as the Black Cats arrived on Wednesday.
But it was leader Virgil van Dijk, a exceptional defensive bedrock as Liverpool have collected the complete set of major prizes, whose dip in performance became the focus during the 1-1 draw.
The Veteran Duo and Contract Extensions
Van Dijk, 34, and Salah, 33, both signed lucrative new two-year deals in the summer, with not one Liverpool eyebrow raised at the prospect of securing the futures to a seasoned pair much approaching the end of their careers than the start.
In fact, it was a moment of optimism - but now there is no escaping the brutal reality that performance has dipped alarmingly for both.
A Leaky Defense and A Costly Refit
Liverpool have been exposed in defence ever since head coach Arne Slot and the club's scouting department undertook a £450m summer refit that has not yet shown anything like its worth.
Concurrently, Van Dijk has started to shed the aura of invulnerability he has possessed since his £75m move from Southampton in January 2018.
Van Dijk has faced additional challenges by defensive partner Ibrahima Konate's dramatic dip, along with Milos Kerkez failing to settle at left-back. But the great Dutchman has also struggled badly, as demonstrated by his panic-stricken handball that resulted in a penalty in the heavy Champions League loss to PSV Eindhoven at Anfield.
A Sequence That Summed Up The Problem
It was captured in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a deserved lead, Van Dijk surrendering the ball before standing off 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 curious trait of turning his back on the ball, sometimes to Liverpool's disadvantage.
Misfortune at the finale, yes, but it was a situation Van Dijk provoked with his unusual failure to make a decisive move, Sunderland's Talbi capitalising.
"Van Dijk surrenders possession 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 dominant, but right now he's slipping up and hesitating."
Performance Metrics and A Lack of Command
As with Salah, a player of Van Dijk's pedigree must not be discarded after winning two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a glittering Liverpool career.
He has, though, looked a faded version of his usual imperious self this season, with the poest ball recovery rate 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 preserve alone in a Liverpool team packed with experience, it was lacking here. No-one was rousing a team that once again looked bewildered to seize the initiative by the scruff of the neck.
Van Dijk's poor display, which ended with him being used as the desperate measure of acting as an emergency striker, was symptomatic of a deeply underwhelming Liverpool performance - which made Sunday's win at West Ham seem like the anomaly rather than the norm.
A Side Lacking Inspiration
Slot persisted with the side that ended a run of nine losses in 12 games at London Stadium, Salah once more starting on the sidelines.
The Egyptian came on at the start of the second half as the Kop looked to him for inspiration. It was not forthcoming, with £125m Alexander Isak also quiet 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 taken a deflection off Nordi Mukiele to set up what Liverpool hoped would be a grandstand finish.
Stoppage-time tension came - but at the other end. Liverpool were only saved from humiliation 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.
Credit Due and The Road Forward
Slot and his struggling title-holders 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 sluggish, unimaginative and devoid of creativity. Even the typical final push after the equaliser carried little conviction. Displays 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 seeing the results for a summer of notable ambition 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 symptomatic of the manner in which they have grown into 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 back to the drawing board.
