Good evening and welcome to Eurosport's LIVE coverage of the Copa del Rey clash between Real Murcia and Barcelona. We'll bring you all the action as it happens. Kick off is at 8.30pm.

The Catalans stepped thing up in the second half, with their quality shining through in the end. The second leg will be played in over a month's time, but there's no chance of Real Murcia overturning a three-goal deficit at the Camp Nou. Deulofeu was the stand out for Barca.

FULL TIME: Real Murcia 0-3 Barcelona

This has been a much better second half performance from Barcelona. They looked a little unsure of themselves before the break, but they have upped things in the second period of play.

Well, this is a strange one. Roberto has just hit the ground with cramp. He's only been on the pitch for about 10 minutes. Or is it an injury? There's a bit of concern for him here.

As I mentioned earlier in the evening, there are a lot of people who think the Copa ties at this stage should be just one leg. More upsets that way. That hasn't been a factor here, though.

Credit to the home side, Real Murcia are still showing some attacking intent on the counter attack. This is a two legged contest, so maybe they think a goal would give them a lifeline.

Cillessen is having to stay alert here. The Dutch goalkeeper is called into action, making a double save to prevent Murcia from finding the net and keeping his sheet clean.

ALCACER MISTIMES HIS LEAP! The cross from Roberto was a good one, but the Barcelona striker couldn't make contact. He probably should have directed a header on goal.

The changes to both teams have sucked the flow and tempo out of this game, but it's still Barcelona who are dictating things, controlling possession and probing on the edge of the box.

It looks like Barcelona are going to make another change here. They're going to throw on another youngster, giving them the chance at a first team outing with the game won.

One player who has been rather quiet is Semedo. You might expect that this game would be a chance for the attacking full back to stretch his legs but it hasn't happened.

Of course, the reason there's a place available on the right side of the Barcelona attack at the moment is due to the injury suffered by Dembele a few weeks ago. He'll be out for a while.

Is that change from Valverde a sign that Deulofeu is in his plans for the game against Athleic Bilbao at the San Mames this weekend? Could he be handed the spot on the right side?

A couple changes for Barcelona, with Roberto and Rakitic coming on. Deulofeu and Alena have been replaced for the Catalans. Deulofeu will be pleased with his evening.

Valverde will surely be impressed by the performance of Arnaiz. We expected Alena to be the youngster to cause Real Murcia damage, but it's been Arnaiz who has made the impression.

This second half has been much better from Barcelona. There has been an intensity and an urgency to their play that was missing in the opening 45 minutes. They've upped their game.
