That is all from us for tonight and that is all for football for a few days...
.. nah just joking. Of course there's more football tomorrow as Wolves take on Crystal Palace in the Premier League.
That's it from us, see you later!
'A good performance'
Arsenal 3-0 Dundalk
Arsenal defender Cedric: "We knew about the difficulties of the opposition, we knew we needed to be patient. We waited, we kept going, everyone was giving their best and once we scored the first goal, we immediately got the second and the game opened up, so it was a good performance."
'We were at it from the beginning'
Arsenal 3-0 Dundalk
Arsenal boss Mikel Arteta, speaking to BT Sport: "We made it look easy because we were very disciplined, took it seriously and were at it from the beginning.
"We made a lot of changes, gave opportunities to other players and I think they performed well.
"We have a large squad and I wanted to give opportunities to everybody. Today they showed they were prepared when I need them and today they made it more difficult for me for selection.
"Sometimes it is about the quality, sometimes it is about the tactical plan for the game. I am very pleased with the performance today.
"We missed Willian the last couple of weeks, he had a very short pre-season. He needs that bit of rhythm. He looked good today, great to get some minutes in his legs.
"After losing the way we lost against Leicester it was painful. It took us a few days to react but good to respond straight away with a win and now we go to Old Trafford and try to win again."
Morelos equals McCoist's record as Rangers win
.Copyright: .
Alfredo Morelos equalled Ally McCoist's European scoring record for Rangers to end a frustrating night against Lech Poznan with a one-goal victory.
The Colombian striker came off the bench to head in a Borna Barisic cross for his 21st goal in 36 European games.
It means Rangers and Benfica, 3-0 winners over Standard Liege, top Group D after two successive wins.
Arsenal goalscorer Joe Willock, speaking to BT Sport: "Happy to get a win. I thought we played well. Every team is a struggle in Europe, we had to stick to our plan and I felt we did that.
"I am grateful to play for this team, to start from the beginning makes me happy and a proud moment for my family. Happy for the team and happy to score as well.
"He [Mikel Arteta] just told me to keep working hard. I told him I want to fight for my position and hopefully I will get an opportunity again."
Runar Runarsson barely had a save to make but he kept a clean sheet and that's a big positive for Arsenal after a run of six home games without one stretching back to 1 July.

All very routine at Emirates but how about this. Remember Kemar Roofe's long-range goal for Rangers last week in the Europa League? That set a record for the furthest a goal has been scored in the competition.
Well, a week later the record has been broken with ex-Wigan man Jordi Gomez scoring for Omonia Nicosia against PSV from 56 metres.
FULL-TIME
Arsenal 3-0 Dundalk
All over as Arsenal take the win.
It was ultimately comfortable but credit to Dundalk who defended so well for so long against the Gunners.

Arsenal 3-0 Dundalk
Reiss Nelson bends an effort just wide of the far post. Arsenal are plugging away trying to get a fourth but Dundalk have done a good job of keeping the scoring down after it looked like the Gunners would run away with this after their quickfire double before half time.

Arsenal 3-0 Dundalk
Nice work on the right by Willian and Andy Boyle has to head behind his cross to hand Arsenal a corner. It's their seventh of the game but only their first in this half.

Mark Carolan: It doesn't look like there's anyone else on that bus with Mourinho. Unless they're all at the back messing about.

Ainsley Maitland-Niles pulls the ball back to Kieran Tierney on the edge of the box but his first-time effort is a poor as it flies well over the bar.

Folarin Balogun looks very eager. He tries a backheel inside the box but it doesn't quite come off but got to admire the desire to try clever things.
SUBSTITUTION
Arsenal 3-0 Dundalk
A chance to see one of Arsenal's promising youngsters in action as Folarin Balogun comes on for his debut. The forward replaces Eddie Nketiah while Kieran Tierney is on for Granit Xhaka.
Keepers keeping an eye on each other
Arsenal 3-0 Dundalk
A couple of catches from corners but otherwise it has been a very quiet game for Runar Runarsson. He's done what he's needed to do, which is not a lot.
