Two more El Clasico dates have been added to the calendar after Friday's draw revealed Copa del Rey titleholders Barcelona will meet Real Madrid across two legs in this year's semi-finals.
Real Betis and Valencia will contend for the other slot in this season's final following Friday's draw announcement, with Betis hoping to feature in the showpiece for the first time since they won the tournament in 2005.
Real were the last team to qualify for the last four, beating Girona 3-1 at the Estadi Montilivi on Thursday. Santiago Solari's side advanced with a 7-3 aggregate win and may consider the Copa their best chance at a title this season.
