A quick summary...

Federico Valverde slotted in the winner for Real after Ansu Fati's late equaliser forced extra-time in Saudi Arabia.

Vinicius Junior had put Real ahead in the first half when he was slipped in by Karim Benzema but Luuk de Jong equalised when he bundled it in from close range off the post.

Substitute Fati scored with seven minutes remaining after Benzema had fired Real 2-1 up in the second half of normal time.

Valverde then finished off a slick counter-attacking move by Real Madrid to get the job done.

That was a proper El Clasico.

Real Madrid will play the winner between Atletico Madrid and Athletic Bilbao, who go head-to-head in the other semi-final tomorrow.

The final takes place on Sunday.

Real Madrid are through to the Spanish Super Cup final!

Ousmane Dembele curls it in...Thibaut Courtois claims it!

Real Madrid break!

They have numbers, the goalkeeper comes off his line but Rodrygo puts it wide. That would have been it!

CHANCE!!!

Ousmane Dembele lifts it in and Ansu Fati tries an overhead from a few yards out but he's scuffed it!!!!

Barcelona look down and out. They haven't really created much in the last 15 minutes or so.

Eder Militao has to do a bit of defending on the byline now but it's out for a goal kick.

Eduardo Camavinga is in behind again but Marc-Andre ter Stegen gobbles it up with Karim Benzema lurking in the middle, waiting for the pull back which doesn't come.

Jordi Alba feeds in Memphis Depay but Lucas Vazquez does enough to force him wide. Real win it back and Karim Benzema sets off Eduardo Camavinga. His cross to Rodrygo is a poor one.

Barca switch it from left to right... can they create something here?

Karim Benzema makes another run off the shoulder and it's lifted over the top for him. His touch lets him down.

Barca need to get hold of the ball.

Karim Benzema cuts it back in the middle. Toni Kroos picks it up, flicks it ahead of him but the touch is too heavy. He ends up giving away a foul and Barca will take it quickly.

Ansu Fati goes down in a bundle at the other end, claiming a penalty off Lucas Vazquez but he won't get anything.

Vinicius Junior's day is done with cramp. On comes Eduardo Camavinga.

Inchesssss!

Abde Ezzalzouli strikes it cleanly from the edge of the box and it's just wide of the far post!

Barca just need that one chance...

Real are taking the sting out of it a bit - passing it around the back, controlling possession and killing time as much as possible.

Vinicius Junior is down with cramp.

Pedri gives it away just outside the box but Casemiro's attempted chip floats right into the keeper's arms.

Here we go again. Last chance for Barca.

Karim Benzema almost feeds in Ferland Mendy but it's intercepted just in time!

Quick break now before we get the final stage under way.

A minute to go in the first half of extra-time. What have Barcelona got? They've come from behind twice already in this match.

Karim Benzema has hurt his shoulder and he looks in discomfort but he should be fine to carry on.
