Liverpool look set to have Fabinho in central defence against Bayern Munich on Tuesday in the absence of suspended Virgil Van Dijk, while there are doubts over Roberto Firmino.
Van Dijk must serve a one-match ban and - with there having been no sign of Dejan Lovren [hamstring] in training on Monday and Joe Gomez (broken leg) still out - midfielder Fabinho is poised to be deployed alongside Joel Matip at the back in the Champions League last-16 first leg at Anfield.
Forward Firmino was also not involved on Monday, due to a virus, and will be assessed.
Winger Xherdan Shaqiri, a former Bayern player, could make his return to action after missing the 3-0 Premier League win over Bournemouth because of an abdominal injury.
Meanwhile Jordan Henderson has backed Liverpool to cope in Van Dijk's absence - and declared himself ready to play at centre-back if asked.
Reds captain Henderson said: "Of course, he is a massive miss. I think you can see how important he is for us as a team.
"But at the same time I feel as though we have enough quality in the team to be able to cope with it tomorrow night.
"And it is not just relying on our two centre-halves to defend - it is up to the whole team to defend really, and we do it together.
"So whoever plays there, I am sure they will know the role and what's expected of them."
