A Diminished Presence of His Imperious Self - Van Dijk Fights Waning Influence
The intense attention that has been trained on one global Liverpool icon switched to another on Anfield's fresh desperate night.
Mohamed Salah has faced examination for his subpar performances this season - and was consigned to the bench for the second successive Premier League game as the Black Cats arrived on Wednesday.
But it was captain Virgil van Dijk, a peerless defensive rock as Liverpool have secured the array of top honors, whose struggles came under the microscope during the 1-1 draw.
The Seasoned Stars and Renewed Terms
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 offering extensions to a seasoned pair much nearer to the end of their careers than the start.
In fact, it was a moment of optimism - but now there is no avoiding the stark fact that levels have fallen worryingly for both.
Backline Issues and Summer Spending
Liverpool have been exposed in defence ever since head coach Arne Slot and the club's recruitment team began a £450m summer refit that has still to demonstrate anything like a good return.
Concurrently, Van Dijk has started to shed the aura of invulnerability he has carried since his £75m switch from Southampton in January 2018.
Van Dijk has faced additional challenges by center-back colleague Ibrahima Konate's dramatic dip, along with Milos Kerkez failing to settle at left-back. But the esteemed defender has also struggled badly, as proved by his desperate handball that gave away a penalty in the significant Champions League loss to PSV Eindhoven at Anfield.
An Incident That Encapsulated The Problem
It was encapsulated in the 67th minute on Wednesday when Chemsdine Talbi gave Sunderland a deserved lead, Van Dijk losing possession before standing off and turning his back on a 25-yard shot that struck him and floated 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.
Misfortune at the end, yes, but it was a situation Van Dijk courted 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 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 was impeccable. Every game he was dominant, but right now he's making mistakes and doubting himself."
The Numbers and A Leadership Void
As with Salah, a player of Van Dijk's stature must not be written off after claiming two Premier Leagues, the Champions League, the FA Cup and two EFL Cups in a stellar Liverpool career.
He has, though, looked a shadow of his usual commanding presence this season, with the poest ball recovery rate per game during his Liverpool career, while key defensive stats are also down on last season.
And, while leadership should not be Van Dijk's exclusive domain 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 initiative.
Van Dijk's poor display, which ended with him being used as the desperate measure of acting as an makeshift forward, was symptomatic of a horribly mediocre Liverpool performance - which made Sunday's win at West Ham seem like the exception rather than the standard.
A Side Lacking Inspiration
Slot stayed with the side that halted a run of nine losses in 12 games at London Stadium, Salah once more starting on the sidelines.
The Egyptian emerged at the start of the second half as the Kop turned to him for inspiration. It failed to materialize, with £125m Alexander Isak also quiet after scoring his first with his first league goal for Liverpool on Sunday.
Slot would have been under even more pressure had Florian Wirtz's 81st-minute shot not deflected in off Nordi Mukiele to set up what Liverpool hoped would be a grandstand finish.
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 dribbled past keeper Alisson.
Credit Due and The Road Forward
Slot and his struggling title-holders ultimately had to settle for a draw knowing it could have been worse, with Alisson lucky 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, labored 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 fallen apart.
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 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 frustrated they left Anfield without adding two more to their tally.
For Slot and Liverpool, it is back to the drawing board.
