turned on the style on Saturday afternoon as they thrashed League Two side Accrington Stanley third round. Diogo Jota, Trent Alexander-Arnold, Jayden Danns and Federico Chiesa grabbed the goals in a one-sided encounter as a host of Reds stars impressed.
Those standout performances have given Liverpool boss a headache ahead of his side's return to the Premier League, with the Merseyside giants travelling to Nottingham Forest on Tuesday evening.
And Express Sport takes a look at four key Reds players who are in danger of being dropped by the Dutchman.
Andy RobertsonAndy Robertson has endured a tough campaign after returning to pre-season training late and playing catch-up on his team-mates.
And he is now being pushed by Kostas Tsimikas, who played the full 90 against Accrington. The Greece international looked assured in the backline and pushed forward whenever the opportunity arose.
Liverpool have been tipped to sign a new left-back who could eventually replace Robertson. And the Scottish star is no longer guaranteed to start the biggest matches for his team with Tsimikas breathing down his neck.
Ryan GravenberchRyan Gravenberch only kick-started his Liverpool career after Slot arrived, with the midfielder struggling at times under former boss Jurgen Klopp.
But 22-year-old Tyler Morton showed on Saturday that he is more than capable of stepping up and filling in for the former Bayern Munich man in the centre of the pitch.
Morton looked comfortable in possession as he dictated play, and will be desperate for his chance in the Premier League after previously excelling during loan spells with Hull and Blackburn.
Cody GakpoSlot for his side's FA Cup clash this weekend as the winger became the youngest player ever to represent Liverpool at the age of 16 and 135 days. And the teenager dazzled with his silky skills.
Slot may be reluctant to throw Ngumoha into a Premier League line up due to his age but will earmark him for more minutes in the FA Cup this season.
Summer signing Federico Chiesa could be in contention for a league start in the coming weeks, however, after producing a sublime second half performance on Saturday following his arrival off the bench at the break.
And Cody Gakpo will be watching on closely after nailing down his place on the left wing under Slot. Gakpo has stepped it up a gear this season, but could still be dropped if Chiesa can rediscover the form that persuaded the Reds to sign him in the first place.
Luis DiazLuis Diaz has plenty of competition for a starting place, whether he plays as a winger or a striker. He could miss out to Diogo Jota or Darwin Nunez in upcoming matches, with both players causing chaos in the Accrington defence despite failing to hit their top form against the League Two outfit.
Danns was also menacing during his 20-minute cameo appearance and will feel he has what it takes to play Premier League football this season.
