Where we are right now, I believe is our longest trophy drought ever under a single manager.
If we fail to win anything this year it'll be our longest trophy drought since the 60s when we went 15 years without anything, and 5 managers.
I'd love to see Arsene win something else again, but right now I think we have too many of the wrong people pulling the strings at Arsenal for that to really happen until something meaningful changes in the structure / management of the club. Too many crap strategies and policies over the last 7-8 years, and too little foresight, we're past the point of no-return.
