**Alisson Becker**, **Jeremie Frimpong** and **Giovanni Leoni** are confirmed absentees due to recent injuries.
**Ryan Gravenberch** and **Alexander Isak** missed last weekend's 3-2 defeat by Brentford, as they recovered from fitness issues, while **Curtis Jones** was withdrawn during the second half of that game. The trio are doubts for this tie.
On the latter, Arne Slot said post-match: "He asked to be taken off but he walked off instead of needing a lot of treatment, so I have to wait and see."
**Hugo Ekitike**'s one-match suspension for a red card in the previous round versus Southampton was served in the league and he is eligible for selection here.
Goalkeeper **Freddie Woodman,** son of Bromley manager and former Palace player Andy Woodman, could make his competitive debut for the Reds, with Slot in the habit of rotating out their first-choice 'keeper - currently **Giorgi Mamardashvili** - in the League Cup.
Ahead of the tie, Woodman told the Liverpool club website: "When I signed for this club, if I could have just got one game - that was the dream and ambition.
"Hopefully Wednesday night I can make that happen. But also getting a result and getting through to the next round, that's the importance of the game and of the competition."
