Who said Europa League Thursdays are boring?
That's it from us, see you later.
Arsenal 1-2 Ostersunds FK (4-2 agg)
Arsenal boss Arsene Wenger, speaking to BT Sport: "You can call it complacency, yes, lack of focus and lack of urgency.
"We prepared the game very well because I have enough experience that in these kind of games you have to do the job.
"They are a good side but overall we responded well in the second half."
Just waiting to hopefully hear some reaction from Arsene Wenger.
A defeat at home to Ostersunds FK is not exactly ideal preparations for Sunday's League Cup final with Manchester City.

Well done Ostersunds. All credit to you. Brave showing tonight. Wonderful European campaign. Good luck for rest of domestic season. Be great to have you back in European competition again. Take a bow Graham Potter.
Mark, Anglesey
Knowing Arsenal's lack of consistency they'll now go and win the cup on the weekend.
Callum in Kent
Man City must be quaking in their boots. Mwahaha.

Arsenal 1-2 Ostersunds FK (4-2 agg)
Ostersunds FK boss Graham Potter, speaking to BT Sport: "I am very, very proud of the players and the supporters. To play in the manner we did I felt we showed real courage and bravery and played some good football against a top team.
"At 2-0 we thought we had a chance. We played well, won the game but it was just short of the miracle.
"Apart from the first 20 minutes at home we went toe-to-toe with Arsenal which is no mean feat considering where we have come from.
"It is a learning experience we have been having. It was the first time we were playing in the last-32. Over the course of the game we have shown what we are about and what we are trying to do. Today is a day to be proud of what we did over the two matches."

Theo Richards: Great tactics by Wenger tonight. Lulling Man City into a false sense of security for the final on Sunday. Well played arsenal #winkwink, external
Alphonse Rawlinson: The Mighty Ducks, The Crazy Gang and now Ostersunds, sport loves an upset and boy did they give us one. Take a bow Ostersunds a credit to your nation
Isham: If Graham Potter’s men can defeat Arsenal tonight, think what Guardiola’s men will do this coming weekend. Scary

Arsenal midfielder Jack Wilshere, speaking to BT Sport: "We were nowhere near it and not good enough. We are through and that is all that counts. We will see who we get tomorrow and refocus on the big game on Sunday."
Underestimate them? "Maybe. When you are 3-0 up in a two legged game you have to go again. it is only half time and we maybe underestimated them a little but. We were not good enough, we will accept that and move on.
"We are through, that is probably the only positive."
Arsenal 1-2 Ostersunds FK (4-2 agg)
Ostersunds FK's players have just been over to the away end to applaud the travelling fans, who are having a right party in the away end, which is still full to the brim. They're rightly savouring this moment.
Borussia Dortmund are through against Atalanta largely thanks to Marcel Schmelzer's late goal.
The Italians dominated the game but just couldn't put Dortmund away. It finished 4-3 on aggregate.
Lorenzo Melgarejo has raised hopes of a late Spartak Moscow fightback. They now lead 2-1 at Athletic Bilbao.
The La Liga side are 4-3 up on aggregate. Another goal for the Russians would take the game in to extra-time.

Credit to Ostersunds! But as for Arsenal, the only way they are going to win the Europa League is of all the other teams come down with food poisoning! I play Sunday league and I could show more heart and passion than these bunch of losers!
Leon, London.
Tonight's game should serve as an inspiration to all non-league players who have had knock backs. Keep at it, work hard and you can still have a career in the game.........playing for Arsenal!
Stuart
Arsenal have been made to look very ordinary tonight.

Ostersunds FK don't even have the 70 seconds it took them to score twice in the first half remaining. They're heading out of the Europa League but they are moments away from a famous win at the Emirates.

Chance for Danny Welbeck to deny Ostersunds FK victory on the night. He twists and turns inside the area to grab a couple of extra yards of space but then shoots straight at the keeper.
Welbeck's struggles in front of goal continue.
