Zurutuza then levelled four minutes before the break as he powered home Alberto de la Bella's pinpoint cross from the left. Sociedad started the second period the stronger and they got their reward 25 minutes from time when Zuruztuza again timed his run into the box perfectly to connect with Prieto's low cross to the near post.
Madrid's humiliation was complete ten minutes later when substitute Carlos Vela appeared to control the ball with his hand before spinning to fire into the top corner. It was a happier evening for Bar?a as they were 1-0 victors at Villarreal thanks to 19-year-old Sandro Ramirez's debut goal eight minutes from time.
"It is gratifying to see the young guys score, but the most important thing is the victory, " said Enrique. "We kept going until the end. Villarreal defended very well and waited for the counter-attack to cause us problems. "Bar?a completely dominated possession in the opening 45 minutes, but failed to create clear-cut chances as Sergio Asenjo parried a drive from Pedro before turning a deflected Messi free-kick onto the post.
