Arsenal were dumped out of the Europa League and deservedly so. To think it was at the hands of Unai Emery, the man who wasn't good enough to avoid the sack, adds a layer of irony that twists the knife in our guts.
In no uncertain terms, the club's season very much rests on the Europa League and anything but success would spell trouble both in the short and possibly long term too.
Arteta and his staff can consider this first leg something of a let-off but it's a courtesy they won't be afforded again. Play like this next week and it's season over.
In the end, things just didn't work out for Unai and his team in London - perhaps we were a little harsher on him than he deserved
Have we taken a step forward or a step back?
How many times in recent memory have Arsenal had a match wrapped-up inside half-an-hour?
Ahead of Thursday night's must-win clash at Salvia Prague, Mikel Arteta has a big decision to make: does he start Aubameyang or Lacazette?
having toiled long and hard to earn even that meagre breakthrough, we threw it away in a manner it seems only this side is capable of.
For all their pluck in the current campaign, Slavia Prague are not Real Madrid so failing to get a result will be a huge blow.
With European ties of much greater important to come, is this a fixture too far for Arsenal and Liverpool?
