Liverpool welcome back Sadio Mane against Red Star Belgrade in the Champions League but Jordan Henderson and Naby Keita are absent.
Mane missed the 1-0 win at Huddersfield on Saturday with a hand injury but has now returned to training and should start the Group C game at Anfield on Wednesday.
Midfielders Henderson and Keita are both unavailable due to hamstring injuries, while James Milner and Georginio Wijnaldum have shaken off knocks to feature.
Klopp told the club’s website: “Millie looks fine and should be OK, Gini got a knock on his Achilles but should be OK and Sadio trained and should be fine.
“[We have] a couple of problems, but still enough players to choose from.”

Summer signing Fabinho is in line to start with Henderson and Keita absent, while Daniel Sturridge will hope to keep his place up front even though Roberto Firmino is pushing for a recall.
Trent Alexander-Arnold is an option at right-back should Klopp opt to rotate either Joe Gomez or Dejan Lovren in his backline.
