Mikel Oyarzabal slotted home a late penalty to fire Real Sociedad into the Copa del Rey final with a 1-0 win over Basque rivals Athletic Bilbao on Wednesday.
Real Sociedad secured a 2-0 aggregate semi-final triumph over Athletic Bilbao.
American coach Pellegrino Matarazzo has turned La Real’s fortunes around since arriving in December and his side will face Atletico Madrid in the Seville final on April 18, after they ousted Barcelona.
Already holding a 1-0 lead from the first leg at Athletic’s San Mames, Real Sociedad produced a sturdy display at the Reale Arena to knock out the 24-time winners.
Matarazzo said: “Very proud of what the boys have done, over the past two months, it’s pretty amazing.

“Our first match was on the fourth of January and we just reached the cup final.
“The football we’re playing is effective and we want to continue. We’re in the final and we want to win it.”
Real Sociedad have now not lost in their last 10 derby clashes at home against Athletic, whom they beat in the 2020 final.
