Arsenal make three changes to the team named for the carabao cup first leg at Anfield last week. Takehiro Tomiyasu, Martin Odegaard and Emile Smith Rowe come in for Cedric Soares, Eddie Nketiah and the suspended Granit Xhaka.
Thomas Partey, freshly back from the Africa Cup of Nations with Ghana, takes a place on the bench.
Liverpool make two changes to the XI selected to start against Brentford on Sunday. Caoimhin Kelleher takes over from Alisson in goal, while the injured Alex Oxlade-Chamberlain is replaced by young Kaide Gordon.
Curtis Jones, who came on as a substitute in the first leg, gets a full runout this time, while first-leg starters James Milner and Takumi Minamino drop to the bench.
