Merseyside derbies are always special occasions, but when Liverpool and Everton face off in one of the cup competitions it always seems to crank up the drama.
The two rivals from across Stanley Park come face-to-face for the second time in less than a month having played out a 1-1 draw in December.
Both teams have struggled for consistency since then, and no doubt Toffees boss Sam Allardyce will have a gameplan to stop Jurgen Klopp's free-flowing attacking style in its tracks.
Mohamed Salah and Philippe Coutinho both missed the win over Burnley with injuries, and it remains to be seen as to whether either is fit to start at Anfield.
Both are seen as doubts heading into the derby with thigh and groin injuries respectively in what would be a major blow for Jurgen Klopp.
Jordan Henderson (hamstring), Nathaniel Clyne (back) and Alberto Moreno (ankle) are all definitely ruled out while Daniel Sturridge remains a doubt with a knock.
Neither side have any suspension concerns for this fixture.
LIVERPOOL POTENTIAL STARTING LINE-UP
Having been left on the bench against Burnley, Roberto Firmino should return to the starting XI to lead the line.
He is likely to be flanked by Sadio Mane and Alex Oxlade-Chamberlain should both Salah and Coutinho fail to shake off their respective injury problems.
Virgil van Dijk is eligible to make his debut but it remains to be seen whether he will be thrown into such a big match to make his Reds bow.
Adam Lallana earned his first start of the season against Burnley and is likely to return, with James Milner set to be recalled.
In goal, Klopp has confirmed that Loris Karius will start.
