Defender Joel Matip has not played for the Reds since March but is back in training after hip trouble and could feature from the bench.
The Eagles, like Liverpool, have not made any changes to their starting XI, with Wilfried Zaha on the brink of becoming the London club's all-time top goalscorer.
Crystal Palace: Hennessey; Wan-Bissaka, Van Aanholt, Tomkins, Sakho; Schlupp, McArthur, Milivojevic, Townsend; Zaha, Benteke
Subs: Guaita, Ward, Meyer, Kouyate, Sorloth, Ayew, Kelly
Liverpool: Alisson; Alexander-Arnold, Gomez, Van Dijk, Robertson; Milner, Wijnaldum, Keita; Mane, Salah, Firmino
Subs: Mignolet, Henderson, Sturridge, Moreno, Lallana, Shaqiri, Matip
