After this happened, Orellana was completely ostracised by new manager Marcelino García Toral, and on 1 December 2017 he moved to Eibar also of the Spanish top tier on loan until the following 30 June. The following April, immediately after the Basques confirmed their survival, a permanent €2 million contract was agreed after the pertinent clause was triggered; he scored eight goals in 2019–20 and also provided more assists than anyone in the squad, as they again managed to stay afloat.
