Liverpool midfielder Emre Can returns to the squad ahead of schedule to face Villarreal in the Europa League semi-final second leg at Anfield.
The Germany international was initially ruled out for four weeks with ankle ligament damage mid-April but has recovered sooner than expected.
Manager Jurgen Klopp also has to decide whether to start up front with Daniel Sturridge or stick with Roberto Firmino, as he did in Spain last week, or indeed, start both.
Eric Bailly and Leo Baptistao have both recovered from the injuries that kept them on the sidelines during the 2-0 weekend win over Valencia that saw Villarreal secure a top-four finish.
The Yellow Submarines rested a number of key players at the Mestalla.
Mario, Victor Ruiz, Denis Suarez, Bruno Soriano and top scorer Cedric Bakambu were all excused to keep them fresh for the trip to Anfield.
