Liverpool are sweating over the fitness of Darwin Nunez ahead of Tuesday's FA Cup third-round replay with Wolverhampton Wanderers at Molineux.
The Uruguay international - who scored in the 2-2 draw with Julen Lopetegui's side on January 7 - missed the weekend's loss to Brighton & Hove Albion with an unspecified issue, and his participation in the cup is still shrouded in uncertainty.
Jurgen Klopp is also guaranteed to be without Roberto Firmino, Virgil van Dijk, Arthur, Diogo Jota and Luis Diaz, but Stefan Bajcetic should overcome a knock to the hip to make the squad.
Should the 72-hour turnaround prove too difficult for Nunez to recover during, Cody Gakpo will expect to occupy the striker's spot, with Mohamed Salah likely fending off Ben Doak for another start on the right, but Fabio Carvalho should be in with a chance of displacing Alex Oxlade-Chamberlain.
Despite the presence of Bajcetic, the experience of Fabinho could be preferred at the base of the midfield, especially if Klopp elects to drop the under-performing Thiago Alcantara and Jordan Henderson.
Naby Keita and Harvey Elliott are both candidates to come into the engine room, and the same can be said for Joe Gomez and Kostas Tsimikas in defence, with Andrew Robertson and Joel Matip possibly being sacrificed.
Ibrahima Konate and Trent Alexander-Arnold should not be in any danger of dropping out, while Alisson Becker is also expected to retain possession of the gloves ahead of Caoimhin Kelleher.
Liverpool possible starting lineup: Alisson; Alexander-Arnold, Gomez, Konate, Tsimikas; Keita, Fabinho, Elliott; Salah, Gakpo, Carvalho
