The tricky Bryan Zaragoza nutmegs Gavi, who brings down the Granada forward.

Here come those Granada changes - and there will be three of them.

On come Antonio Puertas, Raul Torrente and Njegos Petrovic, replacing Myrto Uzuni, Gonzalo Villar and Alvaro Fernandez.

Granada surely can't see out victory by playing like this for the remainder of the match.

Manager Paco Lopez is preparing to make changes.

It's all Barcelona. Alejandro Balde is played in on the left but his attempted low cross is cut out for another corner.

It's only cleared as far as Fermin Lopez, who makes a clean contact with a volley but it's straight at Andre Ferreira.

Lamine Yamal's added-time goal has changed the feel of this match and the home crowd are certainly not so relaxed anymore.

Ferran Torres blazes a shot over from distance and, although it doesn't appear to take a touch off any defender, the referee awards a corner, leaving the Granada fans furious.

The hosts clear, preventing any further controversy.

No changes for the second half, but it's a little bit more fiery.

There's a disagreement between a few players, with Gavi at the heart of it, and it takes the referee some time to get everyone settled down again.

Right then, away we go again!

It was quite the first half. Let's hope for more of the same.

Aged 16 years and 87 days old, Lamine Yamal is officially the youngest ever goalscorer in La Liga history.

It was a dream half for Granada for 45 minutes, but Lamine Yamal's late goal has given Barcelona hope heading into the break.

We'll have five minutes of added time at the end of the first half.

Jules Kounde goes down again. That's it, he's not going to be able to continue.

He slams the ground with his fist in frustration and throws some tape to the floor as he exits the pitch.

On comes Ronald Araujo.

Granada have had three touches in the Barcelona penalty area.

Two shots, two goals. It has, up to this point, been a dream first-half for the underdogs.

Jules Kounde is down and receiving some treatment on a leg injury. He'll head off the pitch so that can be given a more thorough examination.

It's all Barcelona once again, but still no way through as we approach half-time.

Fermín Lopez lands a shot on target but it's too close to the goalkeeper.

Andre Ferreira takes no chances and pushes a shot out for a corner.

Just over 10 minutes until the interval, can the hosts take their two-goal advantage into the break?

The Barcelona fans look stunned.

The Granada fans are bouncing.

Not many could have seen this coming...

Robert Lewandowski is absent with a left ankle sprain and it does feel as though Barcelona are missing that presence in the penalty area so far.

Alejandro Balde whips in a cross from the left but no team-mates can get to it, allowing Granada to scramble clear at the back post.

Gavi swivels and unleashes a shot that goes wide of the mark, but the flag is up for an offside against him.

Granada just can't get out.

The pressure is building.

Joao Felix takes aim from outside the box and sends a low drive whistling past the far post.

Barcelona are getting closer...
