The pair are back in the starting line-up having played no part in Sunday’s goalless draw at Everton.
Elsewhere, Georginio Wijnaldum and Joe Gomez are selected by Jürgen Klopp as he makes four changes to the team deployed at Goodison Park.
James Milner and Joel Matip miss out due to knocks, as expected.
Liverpool: Alisson, Alexander-Arnold, Gomez, Van Dijk, Robertson, Fabinho, Henderson, Wijnaldum, Mane, Salah, Firmino.
Subs: Adrian, Lovren, Keita, Oxlade-Chamberlain, Minamino, Origi, Jones, Elliott, Williams.
