Liverpool midfielder Adam Lallana is a doubt for Sunderland match
Liverpool midfielder Adam Lallana remains a doubt for the visit of Sunderland.
The England star injured a groin on international duty on November 15 and missed last week's goalless draw at former club Southampton.
Defender Joe Gomez made his return to competitive action for the Under-23s in midweek after 13 months out with a knee injury but it is too early for him to be considered for first-team selection.
Provisional squad: Karius, Clyne, Lovren, Matip, Milner, Henderson, Can, Wijnaldum, Mane, Firmino, Coutinho, Mignolet, Klavan, Perez, Grujic, Lucas, Stewart, Ejaria, Sturridge, Origi.
