Long gone are the days when Sadio Mane, Roberto Firmino, and Mohamed Salah would tear the Premier League to shreds at Liverpool.

Staggeringly, from 197 games together at Anfield, the long-feared trio would combine for a devastating 338 goals, with Virgil Van Dijk once describing them together in action as a "scary" prospect to defend against.

Now, it's very much a work in progress in attack for Arne Slot's men, with both Alexander Isak and Florian Wirtz remaining goalless in Premier League action since joining.

On top of that, fellow summer recruit Hugo Ekitike has largely blown hot and cold on Merseyside, with no league strikes next to his name from his last five clashes.

Last summer also saw a lot of change in attack in outgoings, with the wasteful Darwin Nunez finally put out of his Anfield misery. But, away from the heavily scapegoated South American, the Reds also waved goodbye to loyal servant Luis Diaz, who is now excelling at Bayern Munich, to Liverpool's ongoing distaste.

Diaz's electric form at Bayern

Next to the memorable frustrations regularly served up by Nunez, Diaz's starring role at Liverpool when he was still there could be viewed as slipping under the radar, somewhat.

Yet, Diaz was still labelled as a "very special" talent at Anfield by Jurgen Klopp for good reason, with the one-time Premier League title winner collecting a standout 41 goals and 23 assists from 148 appearances at Anfield.

Before he was moved on to the Bundesliga, he also chipped in with his most fruitful top-flight season in England, tallying up 13 goals.

That same clinical edge has clearly followed him to Bavaria, with Diaz already up to a bumper 11 goals and five assists in his new shade of red from just 17 clashes.

Worryingly, Isak, Wirtz, and Ekitike only have 11 goal contributions between them back in England, with the Colombian winger proving to be a stroke of genius signing for Vincent Kompany's men at the £65.5m range.

To add insult to injury, all three of those Liverpool underperformers mentioned cost far more to obtain, with the 28-year-old already being hailed as a star who "delivers week in, week out" by his new manager.

Thankfully, Slot and Co could be brewing a homegrown iteration of their former attacker.

Liverpool's homegrown Luis Diaz

One of Diaz's strong points when still situated at Anfield was his ability to line up all along the forward positions, with the malleable Colombian managing to bag eight strikes from 16 appearances as an out-and-out centre-forward, away from regularly completing his duties as a left winger.

The Reds have plenty of exciting young stars in their academy right now, chiefly fellow winger Rio Ngumoha but he's not the focus this time around.

Indeed, another teenager by the name of Keyrol Figueroa is now beginning to make a strong impression on the youth staff.

Like Diaz, he has interchanged between wing and striker duties for Liverpool U21s this season effortlessly, with his "instinctive" nature in front of goal - as it was described by Liverpool academy reporter Lewis Bower - also seeing him score goals and pick up assists aplenty.

While he has predominantly found most of his joy on youth pitches comes from leading the line, with a clinical eight goals powered home from 20 games in that role, Figueroa has also not looked out of place whatsoever on either flank, much like Diaz in his Anfield prime. To put those numbers into perspective, it's more goals than Ngumoha has bagged at the same level, having beaten the goalkeeper on just two occasions in nine U21 fixtures.

He will also want to give a disappointing Isak a run for his money down the line, with a deadly hat-trick bagged against Everton U21s last month no doubt making him an even more popular figure in youth circles in the red half of Merseyside, away from being an adaptable figure.

It would be wild to throw Figueroa into the first team imminently, considering he is just 19 years of age and is only used to the comforts of youth football.

But, if he continues as he is now, it will surely only be a matter of time before he is unleashed, having also been described as a "ruthless" finisher of chances by his U21 boss in Rob Page.

Sky Sports' Jamie Redknapp also hailed Diaz as having a similarly impressive "eye for goal" during his Liverpool playing days, as Slot and Co now hope Figueroa can be as lively in the first team picture as the Colombian down the line.
