Real Madrid have extended their unbeaten run to 40 games after they came from 3-1 down to draw the second leg of their Copa del Rey tie with Sevilla.

Los Rojiblancos, who trailed 3-0 after the first leg at the Bernabeu last week, started quickly with Sergio Escudero firing a shot from the left edge of area which Kiko Casilla punched away.

The Real stand-in keeper was on hand again minutes later to deny Joaquin Correa's low drive as Sevilla sought a way back into the tie.

Casilla was finally beaten in the 10th minute after Pablo Sarabia's cross was turned into his own net by Danilo's diving header.

Toni Kroos almost found an equaliser for Real before half time with a low shot, which flew narrowly wide of David Soria's goal.

However, Los Blancos were able to get back on terms within moments of the restart when Marco Asensio's lone run from the edge of his own area was capped off with a shot through Soria's legs.

Sevilla refused to give up and immediately regained the lead through Stevan Jovetic, the Inter Milan loanee who came on just before half time for his debut.

Jorge Sampaoli's men then gave themselves brief hope of a dramatic comeback as Vicente Iborra's close-range shot gave them a 3-1 lead.

However, that hope was quickly extinguished when Sergio Ramos pulled another goal back from the penalty spot for the visitors following Matias Kranevitter's foul on Casemiro.

Real then managed to hold on to their long-standing unbeaten run after Benzema, on a late substitute, managed to weave his way through the Sevilla defence before beating Soria with the last kick of the game.

The two sides do battle again in La Liga on Sunday.
