Real Sociedad reached the Copa del Rey final for the first time since 1988 as a 1-0 win at Mirandes on Wednesday clinched a 3-1 aggregate semi-final triumph.
The two-time Copa winners have been in outstanding form in recent weeks, climbing to sixth in LaLiga, and a sixth straight win in all competitions ended a 32-year wait to return the showpiece.
La Real will now face either Granada or Athletic Bilbao - in action on Thursday, with Sociedad's Basque rivals 1-0 up - next month after building on a narrow home lead against second-tier Mirandes.
