That's it.

We are into stoppage time here.
Have we seen the last of the goalmouth chances?

Messi tries his luck again, cutting in from the right. However, he pulls his low drilled shot wide.
He and Barca go again.

The maestro then tees up a shot on the edge of the area, but it's a relatively comfortable diving stop by Jaume Domenech in between the sticks.

Poor from Lionel Messi.
Yes, I used "poor" to describe a Messi effort.

Now then.
Barcelona have a free-kick on the edge of the D.

Agonisingly close for Philippe Coutinho, who cuts in from the left before striking a delicious low angled shot that beat Jaume Domenech but also the far post.

Barca still look shell-shocked. It's coming up to 'desperation o'clock'.
They cannot afford to drop anymore points at this stage of the season.
Maxi Gomez
Er...
It just had to be Maxi Gomez.
The forward had previously been involved in at least one goal in five of his six La Liga games against Barcelona - and produced a deft poke to convert Jose Gaya's cross from the left.

Barca are really pressing for this third goal which will probably knock the stuffing out of Valencia, who have produced a decent display at the Nou Camp.

It really is difficult to predict the outcome of the match.
It took 29 minutes for it to come alive - and alive it certainly did become.

Barca have a taste for it now.
Striker Martin Braithwaite, who has not scored since the start of December, produces a header and forces a good save at his near post from Jaume Domenech.
At the other end, Uros Racic's shot appears to come off the keeper's right-hand upright.
Incident o'clock!
Ronald Araujo
What a strike!
Ronald Araujo has probably not scored better.
The ball bounces around the area before the defender produces an outlandish scissor-kick to give Barca the lead.
Gorgeous effort.

What a chance for Denis Cheryshev - the Russian midfielder had the goal at his mercy but sidefoots his shot wide from Goncalo Guedes' cross.

He came on for Sergio Busquets, who appeared to pick up a bit of a knock in the first half.

By the way, in all that confusion Jose Gaya was shown a red card, which was downgraded to yellow by Alejandro Jose Hernandez Hernandez.
It's still 11 v 11. I hope.

What an end to the half.
Barca are somewhat fortunate to be 1-1 coming in at half-time.
Whatever will we witness next?
