A decent ball forward is intercepted just before it gets through to Robert Lewandowski as the hosts look to grab a goal before the break.

A little bit of pressure from Real Madrid now as half time approaches. The visitors are not doing anything inside the final third that is of too much concern for the Barcelona defence, however.

Vinicius Junior clocks the run of Karim Benzema inside the box and bends a cross in for the striker, but it is just ahead of him. Right idea.

Referee Juan Martinez Munuera is vehemently brandishing cards for some minor things and happily waving play on for other, apparently far more savage, indiscretions. It’s certainly contributing to the atmosphere. There’s more than a wee edge about this. Like the whole place is five pints deep.

Robert Lewandowski needed treatment after getting caught by Eder Militao but he is OK to continue.

Just over 10 minutes to go until the break and while there's been no goals it has been an entertaining first half.

Concern for Barcelona here as Robert Lewandowski is down injured.

Superb run by Alejandro Balde. From just over half way he breaks forward, weaving past a number of challenges before his cutback is cleared.

Moments later, Real Madrid have a chance but Karim Benzema cushions his header at the far post at Marc-Andre ter Stegen.

Alejandro Balde is sent into space down the left. He sends a quick ball into the box, it is half cleared and Barcelona keep up the attack as Raphinha finds Robert Lewandowski but he is dispossessed before he can get a shot away.

There's a coming together between Vinicius Junior and Gavi, with the latter getting booked after losing his cool. It is shaping up for at least one red card in this game.

A couple of chances for Vinicius Junior, the second of which he is picked out by a ball over the top and he stretches out a boot but just can't quite reach. He only had the goalkeeper to beat if he'd managed to get a decent connection.

I bet Sergio Busquets doesn’t even get flustered at the checkouts of certain supermarkets as his groceries are hurled furiously towards him. He could be playing in the back garden with his kids, given how unruffled he is amid this maelstrom.

Karim Benzema scored a seven minute hat-trick at the weekend as Real Madrid swept aside Valladolid 6-0. Benzema has been quiet so far, however.

A rare couple of minutes without anything of note being created. As things stand it is Barcelona going through to the final thanks to their 1-0 win in the first leg.

Safe to say the Barca fans weren’t having that run of decisions. Not having them at all.

Things are getting spicy as Barcelona boss Xavi is shown a yellow card as he protests after what appeared to be a foul on Franck Kessie.

Despite plenty of chances, Thibaut Courtois is only now forced into his first save of the night but it is a fairly routine catch from Raphinha's header.

Little over a week on from having Kieran Tierney running the legs off him at Hampden, Dani Carvajal looks like he’s going to have another heavy shift here. Barca have had a few overloads down the Real right now. The visitors can’t afford to keep letting it happen.

What a start to this game!

Another sliding intervention but this time at the other end of the pitch as the ball comes across the face of goal to Vinicius Junior, who has a tap in before Ronald Araujo slides in to block the shot.

The battle between those two is going to be fascinating to watch tonight.

Panic in the Real Madrid box as the visitors make a mess of several chances to clear before Sergi Roberto's shot is blocked.

It is all Barcelona.

Eduardo Camavinga is able to continue for now after getting a bit of treatment.
