The Arsenal board have no choice now, they have to make a change and Unai Emery has to go.
This is a game that Arsenal should have put to bed in the first half but alas, the same old frailties rose to the surface.
Looking at the team sheet it was assumed that Emery went with a back five, which would have been ludicrous.
However, he actually played David Luiz as a defensive midfielder and it worked. Well, until the Brazilian came off injured that is.
The Gunners deserved to go in at half time one up, they were the better team and Frankfurt was poor.
The second half was a completely different game.
Frankfurt went for the jugular and the two goals were hardly a surprise. For some reason the team lost belief and it showed.
One can only imagine what the scoreline would have been if the Germans had started the first half how they started the second.
Emery will get the blame for sure but the set up was just fine in the first half and the players must shoulder a lot of the responsibility tonight.
I doubt Emery sent them out to fall back in the second half and it is bewildering why they did.
It has to be the end now, there is simply no point keeping the Spaniard in position for the Norwich game, the players are clearly not responding to him any more.
There is nothing to lose putting a caretaker manager in for a short time while a permanent replacement is hired.
The thing is this, I am not sure a new manager will make that much of a difference.
The brutal truth is that the team is not good enough, there are too many mediocre players, very little balance in the squad and almost no incentive for the big names to play for the shirt.
If Emery is still in charge in 24 hours time then I do not know what to say anymore. It is no good for his health, no good for the club and certainly no good for the fans.
This was a poor performance overall and it could have been so much better.
