45' + 2' HALF-TIME: ARSENAL 3-0 LEEDS UNITED.
43' Leeds just can't get on the ball at the moment and Arsenal aren't in any hurry to push upfield as they knock it around in their own half. The visitors are closing them down quickly, but haven't been able to win it back.
39' PENALTY TO ARSENAL! Meslier takes too long to play a pass and he's quickly closed down by Saka. He tries to win it back, but goes through the back of the forward, kicking his heel and bringing him down to give away the spot-kick.
37' Leeds are on the front foot after Raphinha gets the better of Cedric down the right and he cuts into the box. He tries to lift a cross into the middle from the byline, but can only pick out Gabriel, who clears his lines.
35' OVERTURNED! Stuart Atwell has been asked to go over to the monitor to have a look at the incident and from the replays, it looks like Saka was already going down when Cooper went across to him so Arsenal don't have a penalty.
34' PENALTY TO ARSENAL! Alioski is trying to pull Saka back, but he shrugs off the defender's challenge to get into the box. Cooper comes across to help and it's clumsy from him and the referee points to the spot when Saka goes down.
32' Arsenal aren't really in any hurry to push forward when they win the ball back as they try to open up some space in behind Leeds in midfield. Cedric can't get past Shackleton though and the hosts are forced back again.
30' Leeds are keeping the ball well at the moment, but all of their possession is in their own half. They're patiently trying to play out from the back, but each time they break forward, they're giving it away with sloppy passes.
28' GREAT BLOCK! Luiz drives forward from the halfway line, holding off Bamford to get into the box. He pulls it back from the byline to pick out Aubameyang, who hits the shot first time. Ayling throws himself in front of it though and it loops up over the bar.
26' CHANCE! Leeds break quickly and Raphinha dribbles past Cedric and cuts inside from the right. He squares it to Harrison, who hits the shot first time, but his effort is straight at Leno.
25' Dallas' cross is lifted into Bamford and he does well to bring it down under pressure from Luiz. He can't find any space for a shot so tries to pick out Klich, but Gabriel clears the danger for Arsenal.
23' Saka plays a one-two with Odegaard to try and open up some space down the right, but they can't get around Alioski. There are some half-hearted shouts for a handball against the defender, but nothing's given.
21' Cooper tries to set him side on the attack by playing a long ball over the top for Raphinha to chase down the right. There's too much on it though and there's nothing he can do to stop it from going out of play.
19' Dallas squares it to Raphinha, but he's quickly closed down by Luiz, so he backheels it into Klich on the edge of the box. He takes the shot first time but leans back as he hits it, sending it high over the bar.
17' Aubameyang has scored four goals in his last four Premier League games at the Emirates, one more than he had in his previous nine home games.
15' Leeds have all of their players sitting back in their own half as Arsenal continue to keep hold of the ball. Ayling manages to nick it off Smith Rowe before giving away possession with a sloppy pass.
12' CHANCE! It's a great cross into the near post from Harrison on the left and Bamford gets ahead of his defender to flick it on at the near post. Leno has it covered though and it's a comfortable save for the keeper.
10' Ayling gives away a free-kick on the left and Saka steps up to take it for Arsenal. He's looking for Gabriel at the near post, but his first touch is poor which gives Cooper the chance to clear his lines.
8' Leeds just can't get a touch on the ball at the moment as Arsenal continue to push forward. The visitors are closing them down high up the pitch, but haven't really been able to break forward.
6' Arsenal break quickly and get a lot of bodies into the box when Xhaka plays it out to Cedric on the left. He whips a cross into the box, but it's pulled back as he couldn't keep the ball in play.
4' Arsenal get in behind Leeds again after winning the ball back in midfield. Aubameyang can't get into space for a shot but squares it to Bellerin on the edge of the box and he fires his shot over the bar as well.
2' Cedric pulls it back for Odegaard in the middle, but his shot is blocked by Ayling. The ball comes back to him though and he touches it on for Smith Rowe, who takes the shot first time but fires it high over the crossbar.
1' Bamford gets the game underway for Leeds!
The teams are out on the pitch now, with kick-off just moments away.
Arsenal are unbeaten in their last 27 home league games against promoted sides (W23 D4), since losing to West Brom and Newcastle in the 2010-11 campaign.
Marcelo Bielsa makes just one change from the team that beat Crystal Palace on Monday. Kalvin Phillips went off with a calf problem in that game so Shackleton comes in for him. Hernandez is also back for Leeds after an injury and starts on the bench.
Mikel Arteta makes five changes to the side that lost to Aston Villa at the weekend. Leno and Luiz both return from suspension, with Ceballos, Odegaard and Aubameyang also coming in. Ryan, Holding, Pepe and Lacazette drop to the bench, while Thomas Partey misses out with a hamstring injury.

After going on a six-match unbeaten run in the Premier League after Christmas, Arsenal have struggled in recent weeks and are winless in their last three outings (D1 L2), but they can go above their opponents if they win today. Leeds have won five of their last eight league games though (L3), including their previous two away matches against Leicester City and Newcastle United.
