Within the space of just 69 seconds, the Swedish side pulled the tie right back into the balance, only for Sead Kolonsiac to rifle home early on in the second-half to make it 2-1 on the night.
Arsenal fans are furious and have taken to Twitter to express their anger, venting their frustrating particularly towards striker Danny Welbeck.
What is going on at the Emirates?!
Östersunds are two up inside 25 minutes against Arsenal.
Ladies and Gentleman, we have a game on our hands!

In a shocking first-half display, the Gunners found themselves in a very sticky situation, as two goals from the Swedes made the atmosphere inside the Emirates turn very sour.
Goals from Ken Sema and an own goal off of Calum Chambers looked to have found Ostersunds a way back into this Europa League clash.
However, the Gunners came out for the second period all cylinders blazing to quickly halt Ostersunds’ excitement, scoring after just two minutes of the restart.
Danny Welbeck is about as sharp as the ball

Polite reminder: I’m not Danny Welbeck. Direct the insults elsewhere please. Thank you.

I say this with all due respect: I’m a better footballer than Danny Welbeck.

Why do I love Danny Welbeck? Because he makes the same decisions I would if I suddenly found myself in control of a professional footballer’s body.

Welbeck leading the line in the Europa League. Finding a new sport to follow.
