Arsene Wenger has had some bad nights during his 21-year tenure at the helm of Arsenal, but last night's defeat to Crystal Palace must rank highly among them.
For the first time in his Arsenal career, the long-serving manager has lost four away games on the bounce and in doing so has seemingly kissed any chance of cracking the top four this season goodbye.
An early goal from Andros Townsend set Palace on their way, and Yohan Cabaye doubled the hosts' advantage early in the second half with a sublime long range effort.
Their misery was compounded when third choice goalkeeper Emiliano Martinez gave away a penalty late on to put the result beyond the reach of the visitors.
Collectively, it was a poor performance, but there was one man that Arsenal fans singled out when they flocked to social media during and after the game, and for once, it wasn't the manager.
Since arriving from Valencia over the summer, Shkodran Mustafi has been one of the few Gunners stars to be able to hold his head up high, but against Palace he looked lost against the strength of Palace forward Christian Benteke.
Furthermore, his partnership alongside Gabriel in the heart of the defence looked as though it was always going to fail.
Even before a ball was kicked last night, fans weren't looking forward to the prospect of the central defensive partnership, and judging by what we saw, they were dead right.
Mustafi's partnership with Laurent Koscielny had been so good that the pair were nicknamed ‘Kostafi’, but since the Frenchman has been missing the German World Cup winner has looked half the player he was earlier in the campaign.
And again, he showed his inability to cope without a more experienced partner, and came in for some serious criticism both during and after the defeat.

Certainly, it now seems that everything is up in the air at the Emirates, and given everything that's going on, all signs seem to be pointing towards wholesale change over the summer.
