Last season's beaten finalists Athletic Bilbao cruised into the last 16 of the Copa del Rey on Wednesday with a 6-0 thrashing of lower league Linense to seal a 8-0 aggregate win.
Ernesto Valverde named a surprisingly strong side and was rewarded with second-half goals from Javier Eraso, Borja Etxeita, Kike Sola, Raul Garcia and Mikel Rico adding to Oscar de Marcos's early opener.
Eibar produced a stunning fightback from a 3-0 first leg deficit to beat 10 man Ponferradina 4-0 to claim their place in Friday's draw.
And Lass Bangoura's strike was enough to seal Rayo Vallecano's place in the last 16 on away goals despite a 3-1 defeat at Getafe.
All three sides join holders Barcelona, Sevilla, Espanyol, Real Betis, Deportivo La Coruna and Cadiz, who were gifted their place in the next round when Real Madrid were thrown out of the competition for fielding an ineligible player, in the last 16.
