It's easy to overreact, twitter is a ridiculous place to be, stopped reading the arsenal carry-on for now.
A smashing at the hands of the league's form team, at their ground, is not something to be too stressed about in our stage of development in my opinion.
We all know the defence needs serious work and it will take time to sort that out, perhaps even longer than it took for Liverpool to do it, given we're unlikely to throw 140m pounds at 2 players to fix the issue. We also know that Emery actually got it into a decent shape towards the end of the unbeaten run, with 3 at the back consistently in the form of Mustafi, Sokratis and Holding, and with Bellerin in cracking form. Holding got injured, Mustafi got injured, Bellerin got injured, Sokratis got suspended, and ever since we've had a makeshift defence with Xhaka, Lichtsteiner, Maitland-Niles and Monreal all filling in out of position for various games, and Koscielny being rushed back in for big minutes after a long time out.
Hoping to see a signing for the defence in January, some clarity on the Ramsey/Ozil situations, and we move forward from there. Really need to grind out some results until we settle on the defence for the rest of the season. And we need Bellerin back......
