Either side could have won that in a crazy finale.
But, a goalless draw will not be enough to ease any pressure from Ronald Koeman.
That's us for tonight. Keep an eye out for the report on the website very shortly.
RED CARD
Ronald Koeman
The Barcelona boss is sent from the sidelines. He is an angry man at the moment,
Post update
Cadiz 0-0 Barcelona
This is a crazy ending.
Sergio Busquets kicks a second ball at one of the Cadiz players. The game is stopped as then hosts continue and slot the ball into the net.
It doesn't stand obviously.

Cadiz 0-0 Barcelona
This is a basketball match.
Gerard Pique now breaks clear, he slips Memphis Depay in again, but - again - the Dutchman miskicks from close range.
Another golden chance.

At the end other end, Memphis Depay has a chance but he heads the ball across goal. Why didn't he go for goal?
Cadiz now attack and Salvi Sanchez has a chance but his shot is blocked. What an ending!

Cadiz 0-0 Barcelona
It's Memphis Depay racing into Cadiz's half.
This looks dangerous until Tomas Alarcon hacks him down from behind 20 yards out.
A free-kick in a dangerous position... but Philippe Coutinho bends his shot wide. Into injury time.

Cadiz are throwing the ball into the box and Barcelona are just whacking it clear.
Wait a minute, Barcelona are breaking....

If anyone is going to win this, it looks like it will be Cadiz.
Barcelona are hanging on.
CLOSE!
Cadiz 0-0 Barcelona
So close.
Ricard Puig's first touch sees him lose the ball and Cadiz are away.
Salvi Sanchez bears down on goal but his low shot is brilliantly saved by the legs of Marc-Andre ter Stegen.
Almost the opener.
SUBSTITUTION
Cadiz 0-0 Barcelona
A last throw of the dice from Koeman,
Sergino Dest is replaced by Ricard Puig,.

Cadiz 0-0 Barcelona
The Cadiz fans smell blood now. They think Barcelona are there for the taking,
The visitors continue to dominate possession though - but they look very short of attacking ideas.
Post update
Cadiz 0-0 Barcelona
What do Barcelona do now then?
Sit back and settle for the point or go for it with a man less?
It could be a crucial last 20 minutes for Koeman.
SUBSTITUTION
Cadiz 0-0 Barcelona
Luuk de Jong pays the price for his namesake's red as he is hauled off and replaced by Philippe Coutinho.
Post update
Cadiz 0-0 Barcelona
No.The red card stands.
Barcelona will be furious with that decision.
They now have 24 minutes to play with 10 men.
RED CARD
Frankie de Jong
Uh oh. Trouble for Barcelona.
Frenkie de Jong stretches for the ball in a tackle with Alfonso Espino.
He appears to win the ball but a yellow card is shown - and that is a second yellow and he is off.
Surely VAR could intervene here?
Post update
Cadiz 0-0 Barcelona
The clock is ticking.
Barcelona have just less than 30 minutes to find the breakthrough here.
Imagine the reaction if they again fail to win... Ronald Koeman may want to stay away from the newspapers.

Samson Okyere: I believe if Barcelona find it difficult to break down Cardiz, Koeman might be tempted to repeat his tactics by playing his center backs as false nine.
Post update
Cadiz 0-0 Barcelona
Shoot, Memphis, shoot.
Depay looks like he is in, from Frankie de Jong's through ball, but he hesitates, messes up his first touch, and the chance is gone.
SUBSTITUTION
Cadiz 0-0 Barcelona
A double change for the hosts.
Alvaro Negredo is replaced by Anthony Lozano in attack, and Alberto Perea comes on for Santiago Arzamendia on the left flank.
An sign of attacking intent from Cadiz. Lozano is swift by the way....

Attacking football.... at last!
This half has been a million miles better than that first half already.
Cadiz suddenly want to attack, Barcelona look dangerous, and we have a game on our hands.
