Liverpool's Diogo Jota is a doubt due to a bruised rib.
Roberto Firmino and Jordan Henderson are not yet fit enough to feature, while Thiago Alcantara is out for the season after hip surgery.
Brentford are boosted by the return of defender Kristoffer Ajer, who has been absent since early February with a calf problem.
Pontus Jansson, Keane Lewis-Potter, Christian Norgaard and Thomas Strakosha remain on the sidelines.
CHRIS SUTTON'S PREDICTION
Liverpool's attack is firing at the moment and I really like the look of their forward line.
