Hello and welcome to LIVE coverage of Barcelona versus Valencia in the first leg of their Copa del Rey semi-final. I’ll bring you the team news and build-up over the next hour, followed by full text commentary.

The final whistle goes and the Camp Nou faithful rise to applaud a truly spectacular performance by their Barcelona side. Lionel Messi's hat-trick and Luis Suarez's haul make it 7-0 on the night, with a second leg still to come. Astonishing. Thanks very much for joining us this evening. Make sure to tune back in for live commentary of the big games around Europe this weekend.

We're into two minutes of additional time in Barcelona. This has been a nightmare of an evening for Gary Neville's Valencia. And the worst thing about it? They have to do it all again in the second leg!

GOOOAAALLL!!! That is a ridiculous finish by Luis Suarez. Barcelona work the corner back into midfield and Turan picks out Suarez in the box, who hits it first time on the turn and squeezes his shot in off the post. 7-0.

Neymar has been excellent tonight as well, but he just can't quite find the goal that his performance deserves. Another shot is deflected behind for a corner.

Turan goes into the book for a nasty challenge. Barca have picked up a strange number of yellows tonight for a team who have dominated from start to finish

GOOOAAALLL!!! Luis Suarez grabs a hat-trick of his own, rising high at the back post and burying a downward header from a tight angle. That was not an easy finish by any means, but the striker made it look simple. 6-0.

Gary Neville glares on the touchline as he watches his team chase shadows around the Camp Nou pitch. He'd have been hoping for something good to shout about after his La Liga travails, but no such luck.

Cheryshev is booked to cap a night of humiliation for the substitute. He probably wants the ground to swallow him up.

Neymar showboats and draws in three defenders before trying to get on the end of a one-two with Suarez. It's just cut-out, but Barcelona's star men are in the mood for goals and aren't happy with 5-0.

I think the final might just be in the bag, FC Barcelona.

GOOOAAALLL!!! Lionel Messi wraps up his hat-trick with a drilled finish that flies past the keeper before he could even move. That's 5-0.

To be fair to Cheryshev, he's been good since coming on - the only player to have even looked like troubling the Barcelona defence for the visitors all evening.

Alba is given a rest and on comes Adriano in his place.

Cheryshev has the ball in the back of the net, but the on-loan Real Madrid man has his goal ruled out for offside. Cue more howls of derision from the home faithful.

Messi beats three, four players on a mazy run, but slips just as he's about to pull the trigger.

Barcelona keep the move alive despite Valencia clearing the corner and centre-back Mathieu drills in a powerful shot that the keeper pushes around the post at full stretch.
