Arsenal fans thought tonight was going to be a formality, but they reckoned without a horrendous display from centre-back Calum Chambers in the first half.
With a 3-0 lead against the minnows Ostersunds, Wenger named a second-string team but they went two goals down in the first 25 minutes – the first an own goal from Chambers.
That cut the aggregate score to 3-2 and threatened a huge shock in a cup that Arsenal probably need to win to qualify for the Champions League.
In fact Robbie Savage on commentary on BT Sport said it would be the biggest European shock that he’d ever seen.
Arsenal fought back into the game by half-time but Jack Wilshere missed a big chance just before half-time and meant the fans had a nervy 15 minutes to contemplate a second-half that no-one would have predicted.
Most of the half-time talk will be about the display of Chambers at the back…
Here are the best reactions to Arsenal fans after a terrible first half from the 23-year-old at the Emirates:
What does Chambers bring to this Arsenal team? Aside from the occasional error. He is not good enough in any way.

How Wenger can believe that Chambers & Holding are anywhere near good enough is totally beyond my intellectual brain cells. League 1 level & that’s being kind #AFCvOST

Embarrassing to watch. Now we know why Wenger doesn't trust Chambers. Welbeck, Iwobi, Kolasinac, Holding all not good enough

Don't like calling players for my own team but ive said it before and will say it again, Chambers is absolutely a liability for us at the back as of late

Our back up defenders are Chambers and Holding ????????????????we don’t deserve to even be in Europe

Chambers had a lot of potential, just like many other players we signed. And just the like the rest that have been hyped up, he’s failed big time.

Name a worse back two than Rob Holding and Calum Chambers
— Owen Barrett (@TherealProwen) February 22, 2018
I’m an @Arsenal fan, but a piece of me wants us to get knocked out! Surely Wenger would get the boot then!
Oh and Callum chambers and holding should not wear our shirt

I would rather play with 10 men than with chambers by far the worst defender i have ever seen!!#ARSOST
