Valencia have brought Maxi Gomez on for Hugo Guillamon. That could prompt a change of shape.

Barcelona bring on Oscar Mingueza for Eric Garcia.

That makes me thing Garcia may have picked up an injury and Barca play Napoli in the second-leg of the Champions League tie on Thursday. It's 1-1 after the first leg.

Here comes another VAR check. Pierre-Emerick Aubameyang has been clutching his ankle after being caught by Mouctar Diakhaby.

The referee goes to the monitor but it's decided the boy Pierre was offside.

We play on...

Pierre-Emerick Aubameyang is on the deck clutching his ankle. He's been caught and that might leave a little mark. He gets up gingerly...

Before I mention those substitutions I can tell you Gavi just forced a save, curling low at the bottom corner.

It was accurate but not too powerful. A solid save. My friends in America would call that "regulation".

We are back underway.

There are a couple of substitutions. I'll bring you those next. I think Barcelona have maybe picked up a key injury...

I believe that goal Valencia had ruled out was the first to ever be chalked off by VAR in La Liga because the ball had gone out for a throw in.

The last time Barcelona were 3-0 up in a La Liga game they drew 3-3 with Celta Vigo.

So who knows...

I know this has nothing to do with Spain but given the sun is shining in Valencia I thought I'd drop this in.

If I'm a player... I'm taking my career to Spain.

Conor will be commentating in the monsoon at Wolves on 5 Live. You can follow that live here and listen in the live page too.

Three shots at goal, three goals.

Efficient stuff from Xavi's men.

He's got them ticking once again.

It's kicking off.

Valencia have the ball in the net but it's chalked out as the ball went out for a Barcelona throw in during the move.

Try telling that to the screaming masses. They want to lash out at someone and right now, it's the man in the middle.

The ball was out by a few inches, there's no doubt. Carlos Soler applied a lovely, acrobatic finish but the history books will not reference it.

A big moment. It's hard to see a way back.

Barcelona have this gripped. There's another one coming...

It's a really, really good team goal when you watch it back.

Dest, Busquets, Dembele, De Jong.... all linked up and fluid.

Slicker than a boyband in the '90s.

Replays of that Pierre-Emerick Aubameyang opener might well frustrate Gooners out there.

It was pretty vintage from the Gabon international.

Some pace to get clear, a touch, head up and he rifled it down the near post and high into the net. Top stuff.

Dare I say it, Valencia are getting a little carried away. They're committing men forward and when the ball gets turned over there's a lot of space to get at their back four.

Sergio Busquets plays a first-time pass to set Barca on their way but they get held up on halfway.

The home side have the ball in the net after some pathetic goalkeeping by Marc-Andre ter Stegen.

Jose Luis Gaya is down the left and he slams a cross in which the Barca keeper palms into his own net. He's luck that Gaya went too early on his overlap and was a yard or two off.
