So, a humiliating night for Gary Neville. The bad news is his side have to face Barcelona again in the return leg next Wednesday. Hopefully they will give the European champions a better game. Thanks for your company. Until next time...

Before tonight Valencia were unbeaten in five matches in the Copa del Rey under Gary Neville, scoring 11 goals and conceding just once. 

You can rip that one up.

Humiliation? Perhaps overused, but maybe not tonight?

Into the closing moments. Valencia need putting out of their misery.

This is a slaughter. Barca make it seven - and Luis Suarez gets his fourth - after Arda feeds the Uruguay forward, who first-time on the turn in off the near post.

They're chanting Luis Enrique's name around the Nou Camp. Barca have been a joy to watch even though they have been playing against 10 men for half the tie. 

Exhibition stuff from Barca. We're into the last 10 minutes. Time for another goal or two from the hosts?

There's a second leg to come at the Mestalla next week. What's the point? Barca are surely through to their sixth final in eight attempts.

Terrible defending by Valencia as they fail to clear the ball inside their own area, Messi wins it back and fires past the keeper who should have saved. It's another hat-trick for Lionel Messi. He could end this match with four or five goals at this rate.

Moments before Messi's second goal, Valencia sent on new loan signing Denis Cheryshev from Real Madrid. You can guess the 'welcome' the Russian winger received from the home fans after his inclusion led to Real being eliminated from the competition in December. 

So, who will be first to get their hat-trick? Messi or Suarez?
