Copa del Rey: Atlético-Barcelona, Celta-Alavés
Barcelona were paired with fellow giants Atlético Madrid in Friday's Copa del Rey semi-final draw, which was held at the Spanish FA's headquarters.
The box-office clash is a meeting of clubs with 38 Copa triumphs between them, while the other last-four tie features two sides who have never lifted the trophy.
Fresh from knocking out Real Madrid in the quarter-finals earlier this week, Celta Vigo will fight it out with Deportivo Alavés for a place in the final.
