Hello and welcome to today's live coverage of the Premier League game between Leeds and Arsenal. Kickoff is at 4.30pm UK time from Elland Road.
Kick-off! We are underway here in a very dull, dark and wet Yorkshire!
All the early action and possession belong to Arsenal, as they force Leeds United back.
Willian penetrates down the left, but his cross into the area is cleared easily by Leeds.
OVER! Leeds finally get the ball and make their way forward. Raphinha fires a shot without conviction and it flies over the bar.
We have seen some sloppy passes early on from both teams.
A nothing shot from Ceballos hits the side-netting for Arsenal. Both teams are still trying to get going.
Leeds build down the left and Alioski crosses to Bamford, who only just cannot get there. Promising!
YELLOW! Dallas is booked for a sloppy challenge on Ceballos. Arsenal have a promising free-kick.
Leeds are certainly making Arsenal work at the moment.
The Pepe set-piece is flicked away for a corner by Dallas. Aubameyang is offside and Leeds have a goal kick.
We are still waiting for the strikers to get going here.
Leeds are onto the fact that they may be able to get some joy down Arsenal's right.
Phillips is cautioned outside his box and Arsenal have a set-piece. It amounts to nothing, as the poorly taken free-kick flies over.
Meslier is awake after a Arsenal build-up down the right. Leeds then counter-attack and Leno is under pressure but does well. ACTION!
Leeds are starting to up the ante! They are putting some good moves together and applying the pressure. They secure a corner.
SAVE by Leno! Good work after another Leeds build-up! Willian was beaten there and that opened up the gap.
It has been a very engaging contest but we could have had more.
Leeds are enjoying most of the possession at the moment. They must really make the most of it. They are trying!
Leeds come again down their left and Arsenal's right. That is where the hole is. This time Leeds mess it up.
Ceballos fouls Harrison and Leeds have a set-piece in a good position. It could have turned out better for Leeds, as Arsenal clears.
HALF-TIME: LEEDS UNITED 0-0 ARSENAL. We are all square at the break, but Leeds deserve to be ahead at this stage. A decent game nevertheless.
We are back underway in the second half.
SUBSTITUTION: A direct swop for Arsenal at the break with Willian being replaced by Nelson. Willian did not really feature in the first half.
Arsenal secure a promising free-kick. Ceballos drifts it in but it's wide of ANYONE Arsenal!
RED CARD! Alioski is down! Is Pepe in trouble? VAR has a look and YES PEPE IS OFF AFTER A HEADBUTT on Alioski.
That was rather silly, unprofessional and stupid! Arsenal are down to 10 men. Madness!
Can Leeds take advantage of the extra man advantage?
SUBSTITUTION: Phillips is down and clutching his knee. Arsenal take advantage of this and make a change. Saka is on for Willock.
Arsenal have reshaped and Leeds are struggling to get through. As much as Leeds want to attack they have to be careful.
In a nutshell Leeds must continue to do what they did before the Pepe Madness.
Leeds are firing from all over the place towards goal. Why are they nervous now? As I say that Leno keeps Arsenal in the game with a stunning save after a shot by Raphinha.
Leeds will regret not winning this game now. It is theirs to lose. The points that got away maybe? Let's see.
Leeds continue to make their way into the area minute after minute, but the final shots are really, really poor!
The Arsenal counter-attack on the other hand look more likely to produce a goal.
SUBSTITUTE: Ayling has been replaced by Rodrigo for Leeds.
Leeds are getting closer and closer, but Arsenal just need one moment of brilliance.
Rodrigo tries to bend it around and into the net, but it flies wide! Close!
NO PENALTY! Aubameyang claims a penalty after going down in the box after a brilliant Arsenal counter-attack. VAR says NO!
We are in for an exciting last few minutes. It looks like we may well see a goal either way, It's end to end stuff now.
YELLOW! Ceballos is fouled by Cooper, who is booked for his troubles.
Leeds build and then Bamford hits the woodwork. Leno was beaten! They then win a corner.
We have a stoppage before the corner, as Leno needs attention. The corner is then cleared.
We will have five minutes of time added on.
If Arsenal can come out of this alive they will be very happy.
YELLOW! Phillips is booked for a foul on Ceballos. Frustration no doubt!
FULL-TIME: LEEDS UNITED 0-0 ARSENAL. Leeds hit the post yet again before proceedings come to an end. We have seen everything but a goal and we remain all square at the break, This was by no means a normal 0-0. Thank you for joining us.
