Joel Matip is absent as the Reds head to Spain for their Champions League tie, but Adam Lallana is in the 23-strong squad for Jurgen Klopp to choose from.
Liverpool will again be without their Cameroonian centre-back, meaning the pairing of Dejan Lovren and Ragnar Klavan are likely to continue after their clean sheet in the win over Southampton.
The rest of the squad from the weekend are all fit to travel, including unused subs Daniel Sturridge and Joe Gomez. Both have been in the news since the victory for their non-participation, though for rather different reasons.
Klopp will again swap goalkeepers, with Loris Karius the No. 1 in Europe, while Gomez is likely to come in at right-back for Trent Alexander-Arnold.
Lallana is included as he looks for a first taste of competitive action since his injury, while fringe players from this season Andy Robertson and Marko Grujic are also on the plane.
There are also spots for Danny Ward and Danny Ings, with both peripheral figures so far in 2017/18.
Travelling squad in full:
Karius, Wijnaldum, Lovren, Milner, Firmino, Coutinho, Salah, Gomez, Henderson, Sturridge, Grujic, Klavan, Moreno, Mane, Lallana, Oxlade-Chamberlain, Mignolet, Can, Robertson, Ings, Solanke, Ward, Alexander-Arnold.
Liverpool are top of Group E heading into the match, one point clear of Sevilla and three above Spartak, as they look to take another step toward the last 16.
An 18-man squad can be named on the night, meaning four travelling players will be left disappointed with non-involvement.
