I love VAR but my word it's causing some talking points. It worked perfectly here tonight though - without it, Spain would have been denied a legitimate equalising goal. It's not as easy as it looks either...

And that's it! What a game! End-to-end, goals, controversy - everything!

The real controversy there was that the linesman put up his flag when he probably shouldn't have done. The entire group has changed in a matter of moments because Iran have just equalised!

It's all a bit hectic now. Players are arguing on the pitch, getting all heated and worked up... and I can't tell if the final whistle might have gone. Hakimi is booked for dissent.

Iago Aspas has equalised for Spain!

VAR has that right, it's so marginal but you can see on the replay that Aspas is just onside.

Spain have the ball in the net from a corner and Aspas scores! The linesman puts his flag up and says it's offside - but it isn't! The replay shows he's on! 

VAR decision pending!

I think it's safe to say Spain have been wasteful here. 

Spain pushing for the equaliser, Morocco equal to everything they throw at them. This will be a brilliant and hard-earned win if Morocco can hang on. 

Ziyach walks off the pitch slowly to be replaced by Bouhaddouz.

Spain are looking for the equaliser now but Morocco have everyone behind the ball. They're still committing little fouls, blocking the space, running faster and harder and longer than any Spain player. They seem quicker of thought too and Spain don't have any solutions.

Silva comes off, Rodrigo comes on. 

WHAT A HEADER!

Morocco have a shock lead! It's an absolutely amazing header! En-Nesyri leaps highest, is stronger than Ramos and powers his header into the top corner! The crowd goes wild!

Great play from Morocco. Skill out wide beats two players, gets the move going and a cross from wide is met by the striker in the middle and he shoots! Morocco want a penalty because it comes off Pique's hand. It's never a penalty. Corner to Morocco.

Morocco are constantly fouling Spain players too, it's really difficult for the referee but it hardly seems fair that they're allowed to get so tight and come through the back of Spain players without threat of yellow card. It just means Spain can't do anything because they either lose the ball or win a free-kick in a largely harmless position.

Isco's final ball has been poor tonight. Everything else is exceptional but the cross into the box keeps being underhit.

It's just this all game long now. Morocco have everyone back, everyone charges at the man on the ball, Spain have to go sideways.  I don't buy that it's admirable either. Anyone can defend like this and get a lucky result.

Morocco are still working so hard off the ball to close every single thing down. Spain make two substitutions: Asensio and Aspas will come on for Costa and Thiago. 

Another substitute for Morocco. Boutaib comes off and En-Neysri is on in his place.

Morocco still have everyone behind the ball, Spain just passing from side to side without really being able to go anywhere else. Costa runs into space, the ball is played down the line by Alba and Thiago is teed up to shoot on the edge of the area! He blasts it way over the bar.

Spain are passing around the Morocco half but it's a little slow... until Isco picks up the pace and links well with Silva on the right.

Martin Keown is criticising them for 'passing to death'. Hmmm.

David Silva is annoying Belhanda by standing near the goalkeeper and the referee has to keep an eye on things. The corner comes in and PIQUE IS THERE! He heads an inch wide of the far post! Great jump.

Morocco still so quick to close down every Spanish pass! The ball is out wide, crossed in and Isco jumps highest! He pushes the ball back the other way to the back post and it's going in! But the defender comes across and heads off the line!

Amrabat puts his forearm up to block Iniesta, whacks him in the face and gives away a free-kick. No yellow card, which would have been his second...

Isco's delivery is really poor.

Dirar is scaring Spain. "Whenever he goes running it's like he's been fired from a gun!" says Martin Keown, with good reason. He's sprinting at 1000mph up the pitch and Spain can't get close to him and it's only the last lines of defence that prevent Dirar causing damage.

Morocco are working so hard here. They defend a corner and six players sprint up the pitch to take advantage of all the space Spain have left. Amrabat spots a chance to shoot and IT'S GOING IN! OFF THE BAR!

What an effort! This is sensational from Morocco. They'll be knackered by the 80th minute though...

Spain have picked up the pace and found some of their rhythm. Morocco defending aggressively in midfield, hounding whoever's on the ball to try and give it back. 

De Gea does well here! The ball is chipped over the top of the Spain defence and the goalie is quick off his line to punch the ball away, right before the Moroccan forward can turn it into a goal.

Morocco want a free-kick for a handball on Pique but the referee doesn't see it despite standing right next to the incident. That would have been in a decent position too. Morocco press high and as soon as Spain get past them drop everyone behind the ball to block all space.  

Morocco do the first bit of attacking again but a cross from wide left goes straight behind for a goal kick. Morocco are pressing high to force Spain long from goal kicks.

We're back! Will Morocco still be quite so wired? Kick-off is delayed to make sure that both matches start at the same time... but now we're off.

Leon Osman and Joleon Lescott have been summoned for the half-time punditry in the BBC's studio, which looks an awful lot like the same studio used in BBC Newsround during the 90s. 

Spain got caught out then by a determined, angry looking Morocco team but had the sheer class and patience to get back into it. I can see more goals coming in the second half!

That was terrific. 

Morocco now pressing high up the pitch to stop Spain passing out from the back so easily. They win a throw-in and the fans go absolutely wild. 

Alba gets up the pitch but gives away a goal kick.

 This graphic tells a story. Spain with heaps of passes but always going forward. Morocco going direct, quickly.

The free-kick is curled into the area, Busquets meets it at the back post but can't connect and Morocco clear. Spain build from the back again. 

Isco runs himself into trouble and it's a late tackle by Boutaib... who hasn't been booked... but the referee doesn't show a yellow card.

Isco takes a ball to feet, turns his man and then nutmegs the next. Brilliant. Spain win a free-kick 35 yards out and that's a clear shirt pull, which again could be a yellow card.

BUSQUETS!!! He's missed a free header from the penalty spot. He had to score there! Morocco survive.

Spain are really piling on the pressure. Busquets is spraying amazing passes out to the wide players, there's movement off the ball, Morocco are feisty and on yellow cards... but Silva's corner is caught by the goalkeeper.

Never mind, Spain are back in the Morocco final third again. Every first touch is perfect here and Iniesta is played in behind the defence again! His cut back is just behind his teammates in the box. 

Spain win another corner as Alba runs in behind.

Spain's passing is really opening up spaces in the Morocco defence... but Costa's poor touch gives away a goal kick. 

Another booking! Da Costa goes in the book for a clear foul on Isco! They're all fired up and it looks like Boussoufa has been booked for dissent, waving his finger in the referee's face. That's four yellows for Morocco already...

Morocco are sitting back and launching long balls for the counter-attack. Amrabat could be away but steps on Ramos' heel and takes the boot off his foot. That's a yellow card and a free-kick for Spain. Ramos is receiving treatment for that one, which looked pretty sore.

Isco has found space on the left wing, lays it back to Alba, who crosses and Morocco might be away! Iniesta slides into a challenge with Belhanda and stops the counter-attacking happening. Isco is causing Morocco real problems on the left wing and Carvajal is turning up wide right to offer a switched pass option too. 

MOROCCO HAVE A ONE V ONE! DE GEA SAVES!

This game is mental! It's a quick throw-in and the centre-backs have been hopelessly exposed by Boutaib, who is through on goal. He's quick, away from the defence but his final touch is too far ahead of him and De Gea has the chance to close it down and block.

Morocco are right at it here!

Isco takes a corner and swings it deep into the box. Pique finds space and meets the cross... but his header is easily saved by the goalkeeper. 

Spain have a big chance to score here! It's four players running at the Morocco back line but Iniesta's shot is blocked and Costa loses it! 

That's a yellow card for Ahmadi for fouling Busquets with a tackle from behind. He'll miss the next World Cup ga... oh. 

And now Isco has been fouled by Amrabat. Spain take the free-kick short and start their passing play again.

ISCO SCORES FOR SPAIN!

What a start! This is a beautiful move by Spain too! Isco plays a one-two, Iniesta takes it on, sprints past one defender and then flicks the pass into the box for Isco. He takes one touch and batters the finish high into the net!

Iniesta tries to make amends for his earlier error but hits an awful shot from 20 yards harmlessly wide and high.

 Spain have woken up. There's zip to the passing and they're running aggressively into 50/50s. And all of a sudden they're in!

Is it harsh to suggest De Gea should have done better there? If he was in a Man Utd shirt I'd expect him to save that every single time but there's this unquantifiable vulnerability to him at international level. 

Morocco are just waiting to counter-attack over and again and Spain aren't enjoying themselves. They're full of confidence.

MOROCCO TAKE THE LEAD!

Wow! That came out of nothing. It's a horrible error by Iniesta and Ramos at the halfway line and Boutaib has the entire half to run into! He sprints towards the box and only has De Gea to beat and you just knew he wasn't going to miss! The ball goes beneath De Gea's outstretched leg and Morocco go one up!

At first look that seems like a decent bit of defending by Hakimi but when you think about it, what he's done there is block the ball with his back and then deliberately batter into Silva to send him flying inside the box. It will never be penalty... but isn't it a foul?

There is so much movement in the Spain midfield. Isco and Iniesta jave dropped back but THERE'S A MISTAKE! MOROCCO ARE AWAY!

Great run from Costa off the ball! He moves into space on the right channel and the ball is played there. Costa turns,m passes back and Silva breaks into the area. He's behind the last man, wide of the goal but nobody is in the area to take advantage of his cross. Warning signs that Spain are getting into this game.

Now. The thing here is that Pique has gone in way too aggressively here, it's off the ground, two-footed and could cause serious injury. But he gets the ball and doesn't really touch the striker at all... but he goes flying (of course) and makes out that he's hurt. He's not, and Pique has gotten away with it.

This game is fiery.

It's all kicking off here! Amrabat is fired up and has had a little battle with Ramos after a collision from a 50/50. The two square up to each other... the fireworks are lit! The referee calms things down. For now.

And now Pique has gone in mega hard on Boutaib! Morocco are going nuts.

Corner to Spain. David Silva will take this and the referee is already telling off defenders for holding Spanish players in the box. 

The corner is headed away and Busquets wins the ball with a tackle from behind, which the referee doesn't like.

Spain move up the pitch and Costa wins a free-kick from his evil alter ego, Da Costa. Spain pass around the opposition half, Carvajal gets forward but loses control and Morocco move it around... but there's a mistake! 

Isco overlaps... but his outside of the boot cross is too close to the goalkeeper.

Morocco have instantly gone into defensive mode and look like they're going to sit deep for most of this one.

Morocco get the first bit of attacking done though and a cross from the left by Hakimi - who is a left-back wearing number two (disgraceful) - goes behind for a goal kick.

BBC 4 works! We're in luck. But does that mean goals? We're about to find out! Spain get the game started.

When really, what they should play, is this:

A hat-trick tonight would put him top of the scorers list. We might be getting ahead of ourselves a little here - Morocco are a decent team and are capable of an upset tonight.

But with Portugal likely to get a victory over Iran, there's just no way they'll settle for a point. The interesting thing about this game will be how Morocco deal with it - do they suddenly turn on the magic now there's no pressure? Or will they have a lack of real motivation and fall victim to Spain's sharp passing?
