Real Madrid will take a small aggregate advantage back to the Santiago Bernabeu in their Clasico tie with Barcelona in the semi final of the Copa del Rey, after the honours were shared at the Nou Camp.
Lucas Vazquez gave the visitors their early lead with a cute finish after some wonderful control and poise from the in-form Karim Benzema at the byline.
After a sloppy start, in which they allowed far too many counter attacks with unforced errors, Barca slowly crept back into the game in the first half and could've had an equaliser when Ivan Rakitic rattled a header onto the bar.
