PENALTY APPEAL
Barcelona 2-1 Sevilla
Ivan Rakitic bursts into the pen area and goes down under the challenge of Sergio Escudero.
No spot-kick says ref Jose Luis Gonzalez Gonzalez.
The official was probably right.

It's just not been Luis Suarez's night.
He's been involved in the good Barcelona attacks, but his final ball has been poor.
Another pass finds a Sevilla player instead of a team-mate in final third.

Johannes Geis, on for about two minutes, gets one in the midriff as Gerard Deulofeu fires goalwards.
That would have stung.

Lionel Messi hasn't had too many chances today, but he manages to test David Soria with a low drive which the keeper dives to palm away.
Good palm!
Simon Kjaer is replaced by German midfielder Johannes Geis.
GOAL - Barcelona 2-1 Sevilla
Paco Alcacer

He's a bit like Alvaro Morata this fella.
Paco Alcacer gets in front of Simon Kjaer to poke in Ivan Rakitic's cross from the right.
His reward is to be replaced by Gerard Deulofeu.
What reward!

Moments later, Gerard Pique who was beaten in the air by Muriel for the goal, drives forward and smacks a 20-yarder off the bar.
GOAL - Barcelona 1-1 Sevilla
Guido Pizarro
Well, they should have heeded my advice.
Guido Pizarro heads into the bottom corner from a corner - brilliant climb by the Argentine.
Moments earlier, Pablo Sarabia was had a shot blocked by Nelson Semedo after he took a little too long on the ball from Luis Muriel's pass.
Anyway, Paulinho is on to save the day for Barca.

Sevilla enjoying a bit of 'keep-ball;' but it ends with Andres Iniesta quarter-backing the ball to Luis Suarez who then finds Paco Alcacer who returns the ball to Suarez who lays the ball to Lionel Messi on the edge of the area who... is tackled.

That's another cracking strike by Luis Muriel.
The Colombian, this time, brushes off two half-hearted challenges and fires over the bar.
One of these will go in if Barca aren't careful.

Time for the players to dry themselves off.

Messi's on one at the Nou Camp.
He teases Jesus Navas on the edge of the area like he's a Man City discard.
Cruel.
Then finds space to clip the ball towards goal - but the ball lands on the netting instead of inside David Soria's goal.

...and it's cleared by Sevilla.
Might ditch these build-up entries.
