Joel Matip is expected to start for the first time in six weeks as Liverpool look to overturn a 1-0 first-leg deficit against Southampton and reach the EFL Cup final.
Defender Matip had been missing because of confusion over his eligibility but is cleared to play.
Southampton could be without key defender Virgil van Dijk (ankle).
Jack Stephens may start in his place as the Saints aim for a first major cup final since 2003.
Matip was included in the provisional Cameroon squad for the Africa Cup of Nations but was one of seven players to say they did not want to play.
