Real Sociedad will face Atletico Madrid in the Copa del Rey final after a 1-0 ​win over Basque rivals Athletic Bilbao on Wednesday ‌sealed a 2-0 aggregate semifinal victory.

Captain Mikel Oyarzabal settled a tight contest at the Reale Arena with a ​spot kick in the 87th minute after referee ​Cesar Soto Grado reviewed the incident on ⁠the pitchside monitor.

Inigo Ruiz de Galarreta was penalized ​for pulling Yangel Herrera's shirt at a corner and ​Oyarzabal fired his effort to the keeper's left as he dived the other way.

La Real controlled possession for much ​of the match but struggled to turn their ​dominance into clear chances, managing four shots on target.

Athletic, without injured ‌winger ⁠Nico Williams, rarely threatened the home side until they tried to make a desperate run late in the second half as they exited the competition.

The ​final will ​be played ⁠at Seville's La Cartuja stadium on April 18, when La Real and Atletico ​meet in the Spanish Cup showpiece ​for the ⁠second time.

The Basque side won their previous final showdown on penalties in 1987 after a 2-2 draw ⁠following ​extra time. They lifted the ​trophy again in 2020.

Atletico won the last of their 10 titles ​in 2013.
