Liverpool manager Jurgen Klopp is optimistic that Roberto Firmino will battle back from a muscular problem in time for Saturday's Premier League clash with Aston Villa.

In what will be Firmino's final Anfield game before he leaves as a free agent, the Brazilian could fittingly end his trophy-laden Merseyside stint with a cameo appearance from the bench, and the same can be said for Alex Oxlade-Chamberlain and James Milner - both of whom will also depart when their contracts expire in June.

Naby Keita represents the fourth and final men's player confirmed to be on his way out on a free transfer, but the Guinea international is plagued by a muscular problem of his own and is more of a doubt.

Keita is being kept company in the treatment room by Thiago Alcantara (hip), Stefan Bajcetic (adductor) and Calvin Ramsay (knee), while Darwin Nunez is also absent after missing Monday's 3-0 win over Leicester City with a toe issue.

Even if Nunez was given the green light to return, the Uruguayan would have likely accepted another bit-part role as Mohamed Salah, Cody Gakpo and Luis Diaz line up in an unchanged attack before Firmino bids farewell off the bench.

Fresh from setting up all three of Liverpool's goals at Leicester, Salah will endeavour to score for the 10th game running at Anfield, and Curtis Jones was the beneficiary of two of his assists on Monday night.

Jones ought to form an untouched engine room with Fabinho and Jordan Henderson, while Andrew Robertson and the reborn Trent Alexander-Arnold continue in the full-back positions.

Saturday's game could also end up being Joel Matip's Merseyside farewell amid links with a summer move elsewhere, but Ibrahima Konate and Virgil van Dijk should continue to pair up in front of Alisson Becker.

Liverpool possible starting lineup: Alisson; Alexander-Arnold, Konate, Van Dijk, Robertson; Henderson, Fabinho, Jones; Salah, Gakpo, Diaz body check tags ::
