Team News of Athletic Bilbao vs Barcelona
Messi came off the bench to play 27 minutes against Real after suffering a thigh injury in the draw with Valencia and Valverde said he was unsure if the Argentine would be ready to start this weekend.
Samuel Umtiti resumed light training last week following knee surgery, while back-up goalkeeper Jasper Cillessen is expected to be sidelined for six weeks with a torn calf muscle.
Ousmane Dembele is expected to be available in Bilbao despite not making the squad against Real following illness and an ankle issue and could start if Messi is not ready.
However, Jordi Alba will serve a one-match suspension after collecting his fifth yellow card of the season.
That could lead to Valverde switching Nelson Semedo to left-back, although Thomas Vermaelen has played in that position this term. Alternatively, the manager could opt for a three-man defence.
Rafinha was lost for the season back in December after tearing the anterior cruciate ligament in his left knee against Atletico.
Barcelona (4-3-3): Ter Stegen; Sergi Roberto, Pique, Lenglet, Semedo; Busquets, Rakitic, Vidal; Coutinho, Suarez, Messi
