Dundalk keeper Gary Rogers tips over Sead Kolasinac's header after good work from Joe Willock on the right.

Another Arsenal corner, Dundalk struggle to clear but eventually manage to deal with the danger.

Dundalk suddenly attack with numbers and Sean Murray misses his shot on the edge of the area but the captain Chris Shields wins a corner when his strike deflects behind.

Runar Runarsson again makes the easy catch from the delivery.

Mikel Arteta looks slightly pensive on the touchline. He may not have been demanding a goal by now but he would certainly have hoped his side would have worked the goalkeeper at least.

Eddie Nketiah tries to work his way through the Dundalk defence but he is closed out.

Dundalk are nailing their gameplan so far. They are staying disciplined and not over committing at the sniff of a chance to get forward.

Reiss Nelson's shot bends just wide of the far post as Arsenal keep up the pressure.

This touchmap graphic provides no surprises with the visitors yet to get inside Arsenal's box.

A good leap by Nicolas Pepe as he rises to meet Sead Kolasinac's cross but his header loops over the bar.

Good defending again from Dundalk as they prevent Reiss Nelson from trying to wriggle his way into the box following a short corner before Sead Kolasinac's cross is cleared.

Better from Arsenal as Joe Willock passes across the face of goal but no-one is there to turn in.

A warning shot for the visitors. They need full focus at all times.

I always remember hearing Danny Cowley - ex-Lincoln and Huddersfield boss - talking about how he broke games down into mini-sections when his sides faced bigger teams and telling his players to see getting through each one as a success.

If Dundalk have the same approach they will be very happy with the first quarter of an hour. They've kept Arsenal at bay.

Andy Boyle gets across to stab away the ball from the feet of Joe Willock inside the box. Nicolas Pepe then hits the corner into the sidenetting. Poor.

Arsenal are building but the visitors defending well so far.

First real effort for Arsenal but the sort of shot that Dundalk will welcome all day long as Nicolas Pepe lashes well over from outside the box.

Nicolas Pepe looks to get away down the right but play is brought back after he is deemed to have handled the ball when first bringing it under control.

Almost 10 minutes in and the Gunners have not yet got a shot off on goal. So far, so good for Dundalk.

Oh it seems Filippo Giovagnoli has now been allowed to take his place in the technical area for Dundalk despite his lack of a Uefa Pro Licence so that will be a boost to the visitors to have their manager watching on.

A good challenge prevents Eddie Nketiah from doing something with the ball when Nicolas Pepe's cross comes to him.

Leicester defender Wes Morgan to BT Sport: "I don't know what was said in the dressing room at half-time but AEK came out a different team and made us work for the three points.

"It was difficult for us in the second half but credit to our boys, we withstood their challenge and saw out the game."

On Wesley Fofana... "He's got great potential. It's a joy to see someone of such a young age performing at such a high level."

What a start this would have been for the visitors!

Patrick McEleney has the ball in the middle of the Arsenal half, no-one closes him down so he tries his luck with a low strike from distance that Runar Runarsson pushes behind.

The Icelandic goalkeeper then catches the ball from the corner.

No surprises to see Dundalk packing the defence. They are happy to let Arsenal have possession anywhere apart from in and around their box.

Filippo Giovagnoli, the Dundalk manager, isn't allowed on the touchline tonight because he doesn't have the Uefa Pro Licence so it is Shane Keegan, the club's scout, who is there in his place to relay instructions.

We're under way at the Emirates.

Right then, rest is for the weak in the Europa League because on we go with our next game - Arsenal against Dundalk.

The players are out on the pitch. What a moment this is for the Irish visitors as they play Arsenal for the first time.

Jose Mourinho made a raft of attacking changes early in the second half and while they looked better going forward they didn't manage a single shot on target at all after the break.

In fact their last shot on target was in the 19th minute. It will be interesting to hear what Mourinho thought of his side's performance.
