Real Sociedad are still looking for their second win of the season after they drew with Levante in La Liga.
The game was largely quiet in terms of goalscoring opportunities and arguably the best fell to Baba Diawara for the hosts early in the second half. He strode into the area only to be foiled by a brave stop from keeper Claudio Bravo.
Sociedad could have scored themselves when Xabi Prieto collected a loose ball inside the Levante penalty area before hitting the post and Carlos Vela failed to connect with the rebound.
With minutes remaining, the hosts almost snatched the points after a free kick from Papakouli Diop rattled the crossbar, but both sides had to settle for a draw.
