I'm not sure that's true. Our points total since 2007/8 has been:
72,75,68,70,73,79,75,71,75
There's no clear trend there. It's been stagnation, not decline.
That is a bigger concern, admittedly. And this is why "Wenger Out" is not a silver bullet. Because if Kronke replaces him with someone who will just keep us bumbling along then that won't necessarily improve the situation.But the wider, bigger picture is Kroenke's track record with his other franchises. They have all dropped off and become mediocre, just drifting along while he raking in the money. Luckily there's no sign of that here...
Kronke Out AND Wenger Out (And Letters Out, obvs)
