Premier League 2017/18: Brighton and Hove Albion 2-1 Arsenal; 5 Talking Points
Two first-half goals from Lewis Dunk and Glenn Murray gave Chris Hughton some respite heading into a series of fixtures that is sure to test their resolve to stay in the English top-flight.
Arsenal, on the other hand, succumbed to their third loss in a week and are now only barely hopefuls of making it into the UEFA Champions League through a high league finish.
Here's what we learnt from the Amex Stadium:
Arsenal's defence not Premier League top-half material
Be it the ageing of Laurent Koscielny, the error-prone-ness of Shkodran Mustafi, the inexperience of Sead Kolasinac and Calum Chambers and the slouchiness of Petr Cech, Arsenal's defence was just plain poor.
Nobody stands tall and commands during a corner-routine anymore, they don't shout and yell instructions as often and they don't draw fouls as they should - despite what the purists might opine.
Arsene Wenger reportedly told Pierre-Emerick Aubameyang that he promised him 'world-class signings' in the summer and unless he signs three or four experienced and commanding defenders, he'd have already let the Gabon man down.
