Good evening and welcome to Eurosport's LIVE coverage of the Copa del Rey quarter final second leg between Real Sociedad and Barcelona. We'll bring you all the action from the Anoeta. Kick-off: 20:15.

That's a huge win for Barcelona. The winless run at the Anoeta is over for them and they will take a well-earned 1-0 lead into the second leg against Real Sociedad at the Camp Nou this week. They were hardly at their best, but they did just enough to get over the line.

FULL TIME: Real Sociedad 0-1 Barcelona

This will be Barcelona's first win at the Anoeta since 2007, but Real Sociedad are pressing forward looking for a last gasp equaliser. There is still a minute to play.

Barcelona are now doing their best to run down the clock. Suarez is down on the ground, Messi is even doing his best to see out this game. The Catalans aren't usually this wary.

Three minutes of stoppage time to be played at the end of the match.

ILLARREMENDI OVER! The freekick delivery into the area was a good one by Canales, but the midfielder rose a little too early and directed his header over the target. Good chance.

Here's a damning statistic for Real Sociedad - they have yet to muster a single shot on goal. Cillessen in the Barcelona goal hasn't had to face a single shot all match long.

NEYMAR GETS LUCKY! The Brazilian is already on a yellow card, and so it was risky to go in with a high boot there. The referee decides not to show him a second booking, though.

Barcelona are just four minutes away from their first win at the Anoeta since 2007. Real Sociedad are unbeaten in their last eight at home to the Catalans.

Now Yuri takes aim from distance but that shot is the result of desperation and it drifts over the crossbar. I just get the feeling that Real Sociedad are running out of ideas.

Time is running out for Real Sociedad if they are to get anything out of this game. And you would think they will need at leat a goal to take to the Camp Nou next week.

This has so far been a really shrewd performance from Barcelona. They are not in the business of entertaining this evening. They simply want to come away from here with a result.

There's the change for La Real that sees Canales come on for Real Sociedad. Can he create something?

NOT FAR AWAY! Messi lines up the freekick 20 yards out, but he sends it over the target. He got his angles right, he just lofted it slightly high. Rulli watched it flash over.

Barcelona win a freekick on the edge of the box, about 20 yards out, after Messi was brought down by Illarramendi. This is a real chance for the away side to add a second goal.

It looks like Real Sociedad are about to make another change. Canales is down on the touchline waiting for the ball to go out of play so that he can come on. Still waiting...

Gomes was too indecisive in the box. He was played in down the left hand channel, but he attempted a drag back instead of taking the shot on first time. He was tackled in the end.

The home side are ringing the changes now, but why didn't they make these alterations to their lineup earlier in the match? They might not have left themselves as much time.

Vela is taken off. The Mexican certainly wasn't at his best this evening, so he can have no complaints about that.
