The tempo of the game has dropped considerably now, with the final whistle in sight. Just a few more minutes for Arsenal's youngsters to make an impression on Arteta.
85'
S. Hoare has scored a goal for Dundalk! Assist by J. Flores.
Hoare's unorthodox header was made possible by the pace and whip on the delivery from Flores, who made it difficult for the Arsenal defenders to intercept his cross.
GOAL!! DUNDALK PULL ANOTHER ONE BACK!! Flores whips a free-kick into the box with plenty of pace and Hoare flicks the ball past Runarsson and in with the back of his head! It's 4-2 now!
83'
M. Azeez enters the game and replaces J. Willock.
Arteta hands out another debut, with Azeez replacing Willock in midfield for Arsenal.
82'
D. Kelly gets yellow.
Dundalk substitute Kelly now goes into the book for an overzealous challenge on Cedric.
80'
F. Balogun has scored a goal for Arsenal! Assist by N. Pépé.
Plenty of credit should go to Pepe as well, who crafted the opportunity with a purposeful drive through the centre before playing a composed pass to Balogun.
GOAL!!! BALOGUN SCORES OFF THE BENCH AGAIN!!! Pepe marauds through the centre and slips a perfectly-weighted ball through for Balogun, who bends an unerring finish into the bottom-right corner past Rogers. It's 4-1 to Arsenal now!
77'
J. Wynne enters the game and replaces M. Duffy.
S. Čolović enters the game and replaces P. McEleney.
C. Shields gets yellow.
B. Cottrell enters the game and replaces E. Smith Rowe.
Shields is the latest player to go into the referee's book as he makes a poor challenge on Balogun.
Keegan makes another couple of changes now, bringing Duffy off for Wynne in the first alteration.
Meanwhile, Smith Rowe is off for the Gunners as Cottrell makes his competitive Arsenal debut.
McEleney also makes way, with Colovic replacing him as Dundalk look for a way back into the contest.
72'
McEleney takes a shot from a very speculative distance, and it predictably ends up comfortably wide of the target.
70'
D. Cleary gets yellow.
Cleary goes into the book for barging Smith Rowe to the floor. He protests, but it's a clear yellow card.
69'
Balogun has a go from outside the box but it's blocked away. It eventually comes to Mari who thumps an effort at goal, but it's an easy save for Rogers in the end.

Description
67'
J. Willock has scored a goal for Arsenal! Assist by F. Balogun.
Substitute Balogun did superbly to hold off the challenge of Gartland with his back to goal before finding Willock at just the right time. Excellent centre-forward play from the youngster.
GOAL!!! WILLOCK MAKES IT 3-1!!! Balogun holds the ball up well in the box and lays it off to Willock, who evades one challenge before drilling a fierce, low effort at goal that is close to Rogers, but the keeper can't get down to it and the ball hits the back of the net!
62'
Dani Ceballos enters the game and replaces Mohamed Elneny.
F. Balogun enters the game and replaces E. Nketiah.
Arteta makes a double-change now, with Elneny replaced by Real Madrid loanee Ceballos in midfield in the first alteration.
Nketiah also makes way, with one young striker replacing another as Balogun comes on.
61'
J. Mountney gets yellow.
Dundalk substitute Mountney steps on the foot of Smith Rowe as he gets to the ball late and is shown a yellow card.
58'
Dundalk have finally got themselves on the ball after a bright start to the second half by the Gunners. They're just keeping it for now, working it around and looking for spaces.
56'
Arsenal have been swarming all over Dundalk since the restart but just haven't quite found that killer final ball. The hosts are keeping a rigid shape at the back.
54'
J. Mountney enters the game and replaces S. Gannon.
D. Kelly enters the game and replaces D. McMillan.
Keegan takes the opportunity to make a second change, replacing Gannon with Mountney as the Dundalk boss searches for an equaliser.
53'
McMillan stayed down in the aftermath of that chance and it looks like he's pulled his hamstring. He can't continue and will be replaced by Kelly.
50'
Elneny's ball into Nketiah on the penalty spot is under-hit but the young striker does well to make something of it and shoots on the swivel, but it's charged down and blocked away.
48'
Arsenal have started the second half much better, pressing higher and looking to win the ball in dangerous positions.
46'
B. Gartland enters the game and replaces A. Boyle.
Keegan makes a half-time change, presumably due to injury, with Boyle coming off for Gartland in defence.
We're back underway for the second half!
45' +1
HALF-TIME: DUNDALK 1-2 ARSENAL
44'
The Gunners have seemed really lethargic since conceding. They've picked up the tempo a little in the last few minutes but they're certainly not playing with the swagger and confidence you'd expect of a team of their stature.
42'
Arsenal press a little higher and Smith Rowe thinks he and Elneny have won the ball between them, but the referee awards a foul Dundalk's way.
38'
Pepe swings a corner into the box from the right and it's all the way to the back post where Mustafi can head into the middle, but Dundalk have enough bodies back to hack clear.
36'
Possession of the ball has been very evenly shared so far. Arteta won't be happy with his side's inability to dominate proceedings to this point.
32'
Arsenal have dropped off and aren't pressing as high as they were in the first 20 minutes or so. Dundalk are getting more space to play out and keep hold of the ball.
30'
J. Willock gets yellow.
Willock can feel aggrieved to be booked as he inadvertently catches McMillan with a stray arm whilst holding off his challenge. That seemed harsh.
28'
Cédric Soares gets yellow.
Cedric takes a heavy touch and Leahy races towards the loose ball, getting there slightly ahead of the Arsenal defender and drawing a foul that sees the Portuguese go into the book.
26'
Pepe draws a foul from Cleary in the Dundalk half, but Arsenal can't make the most of the set-piece. The visitors have lost a little of their momentum since conceding.
24'
Arteta does not look overly pleased on the touchline in the aftermath of that goal. Arsenal were pulled apart there.
22'
J. Flores has scored a goal for Dundalk! Assist by M. Duffy.
Duffy was an integral part of the move that set Flores away into the box, with quick, incisive passing in the build-up to the goal.
GOAL!! DUNDALK HAVE ONE BACK!!! Flores and Duffy exchange passes quickly and the former is released into the Arsenal box on the right. He thumps a powerful strike across goal that beats Runarsson, who got a touch on it, and flies into the bottom-left corner! It's 2-1 now!
20'
Some clever interplay between Maitland-Niles and Smith Rowe on the left releases the latter into space and he steers a low cross in for Pepe, but the Ivorian gets his finish all wrong and smashes over the bar.
18'
Mohamed Elneny has scored a goal for Arsenal! Assist by E. Smith Rowe.
GOAL!!! WHAT A HIT FROM ELNENY!!! Smith Rowe lays the ball back to Elneny on the left around 25 yards out and the midfielder unleashes an absolute thunderbolt that flies into the very top-right corner! That was a magnificent strike! It's 2-0 to Arsenal now!
Smith Rowe was positive, driving at the Dundalk defence on the left and getting into a dangerous position before finding Elneny, who came up with an incredible strike!
14'
Arsenal have been pressing effectively as Dundalk try to play out from the back, and the hosts look uncomfortable with the ball in their own third.
12'
E. Nketiah has scored a goal for Arsenal!
GOAL!! ARSENAL TAKE THE LEAD!! Nketiah charges down a clearance from Boyle and races into the box before lifting the ball cleverly over the onrushing Rogers and over the line! It's 1-0 to Arsenal!
10'
A. Boyle gets yellow.
Nketiah races onto a lovely ball forward from Mari down the left and gets past Boyle, who pulls him down just outside the box and is shown a yellow card.
7'
Smith Rowe presses well and nicks the ball high up the field before charging to the byline and cutting back towards Nketiah, but it's just intercepted and hacked clear.
5'
Nketiah latches onto the ball on the edge of the box and shifts it onto his left before thumping a shot at goal, but it's blocked away well.

We're underway in Dublin!
Hello and welcome to our LIVE coverage of the Europa League fixture between Dundalk and Arsenal at the Aviva Stadium in Dublin.
Arsenal come into this game with their status as group winners already confirmed, having won each of their five matches in the competition so far. Dundalk, meanwhile, are bottom of the group with 0 points and cannot progress to the knockout stages.
Dundalk XI (3-4-2-1): Gary Rogers; Sean Hoare, Andrew Boyle, Daniel Cleary; Sean Gannon, Chris Shields, Jordan Flores, Darragh Leahy; Patrick McEleney, Michael Duffy; David McMillan.
Dundalk substitutes: Jamie Wynne, John Mountney, Daniel Kelly, Gregory Sloggett, Stefan Colovic, Brian Gartland, Cameron Dummigan, Aaron McCarey, James Corcoran.
Arsenal XI (3-4-2-1): Runar Alex Runarsson; Calum Chambers, Shkodran Mustafi, Pablo Mari; Cedric Soares, Joe Willock, Mohamed Elneny, Ainsley Maitland-Niles; Nicolas Pepe, Emile Smith Rowe; Eddie Nketiah.
Arsenal substitutes: Miguel Azeez, Dani Ceballos, Karl Hein, Folarin Balogun, Rob Holding, Ben Cottrell, Bukayo Saka, Matt Macey.
Despite leading at the break, Arsenal have not played to the standards Arteta expects of his team for much of the first half, allowing their opponents nearly 50% possession. The Gunners boss will certainly expect his side to show more energy off the ball and quality on it the second period.
Thank you for joining our coverage, we hope you enjoyed the game. Until next time, goodbye!
Arsenal host Burnley next as they return to Premier League action this weekend, while Dundalk's season is now over following their elimination from the Europa League.
