Looks at the match stats and Barcelona really are dominating as much as you would think.

They have controlled more than 80% possession for much of this contest.

Barcelona have had shooting practice for much of this game. Not that they have exactly been on target.

Ousmane Dembélé is the latest to let rip, but its harmless.

Lionel Messi on the edge of the area twists and turns to try find space.

He finds a slither of sliver of space, but Isaac Carcelén blocks.

This free kick sums up why Barcelonan need that second.

A free kick from deep is floated into the box and falls to Fali, who drills his effort wide. The whistle was blown for a foul before that, so it wouldn't have counted.

Still, Cadiz remain an undeniable threat no matter how much they are being outplayed.

Barcelona will want to make this scoreline more comfortable in a hurry.

They have had two goal disallowed for offside, but Cadiz have also come close on the counter-attack. They remain a danger.

And we are back under way.

No changes from either side.

And that goal also means Messi extends his La Liga record of netting versus the most different opponents to 38.

That was Lionel Messi's 60th goal scored from the penalty spot in La Liga.

That means he is the second player to score 60 La Liga penalty goals, after Cristiano Ronaldo (61).

We do love a Lionel Messi stat, and I have a few for you after that penalty...

Lionel Messi's penalty on his Barcelona-record 506th La Liga appearance is the difference so far.

We are into two minutes of injury time at the end of the first half now.

And again Barcelona have a second ruled out. Perdi this time.

Frenkie de Jong takes the initial shot and it appears that Antoine Griezmann touched the ball on the way through.

Padri pounced after the rebound from Jeremías Ledesma's save eventually found him free in the middle of the area.

That Lionel Messi goal to put Barcelona ahead means he has scored in six consecutive La Liga appearances for the first time since a run of eight from December 2018 to February 2019.

Frenkie de Jong has the ball in the back of the net for Barcelona but it is flagged for offside.

It's not even marginal as he goes too quick to meet a Antoine Griezmann pass from the top of the box.

Huge moment for Cadiz.

The visitors catch Barcelona napping after the opener. It's another of those fine counter attacks, but Rubén Sobrino is off target from right in front after running onto a neat flicked header.

Pedri is sandwiched in a tackle. Isaac Carcelén is the one who brings the Barcelona man down.

Cadiz protest, but it's pretty clear cut.

Cadiz have nine defending on the edge of the area. It is a wall of yellow shirts.

Barcelona try to poke a hole, but every pass is repelled.

And so Lionel Messi tries his luck from distance. And it is a peach of an curling effort, that requires a great save from Jeremías Ledesma.

Cadiz are very much holding Barcelona at bay right now.

What sort of resistance can Cadiz really offer over 90 minutes? Going by recent form, I'd have said not much before kick off.

They have conceded 17 goals during their five game winless run.

The chances are just stacking up for Barcelona now.

Lionel Messi with a low effort, but Jeremías Ledesma is equal to it.
