Athletic Bilbao and Real Sociedad could meet in the Copa del Rey final after the Basque rivals were kept apart in the semi-final draw.

Sociedad secured their place in the last four with a thrilling 4-3 win over Real Madrid at the Santiago Bernabeu on Thursday, with Athletic beating Barcelona 1-0 hours later thanks to a last-gasp Inaki Williams header.

It marked the first time in 65 years that LaLiga's top two clubs were eliminated from the Copa on the same day.

Gaizka Garitano's Athletic will now face Granada, who knocked out holders Valencia in the quarter-finals, while Sociedad will meet Segunda Division side Mirandes.

Athletic and Sociedad will host their respective first legs, which take place on February 12, with the return fixtures scheduled for March 4.

The final is expected to be held on April 18 at La Cartuja in Seville, which last hosted a major club football match in 2003, when it staged the UEFA Cup final between Porto and Celtic.
