Even at the end of last season, though most Gooners would have felt disappointment, I don't think anyone would have expected to experience this crushing uncertainty over the very foundations of this great club.
Some people like having a scapegoat to focus their frustrations on. If you are such a person, I think we can trace back all the current problems to the takeover bid by Kroenke. That led to the rift in the board, which led to Dein's departure, which has led to Arsene refusing to commit, and ultimately Henry leaving to Barca. What this might bring next is also worrying...
So say it with me chaps: "It's all Kroenke's fault!"
