@Taz, you dont get Impunity's point (who is, btw, an Arsenal fan). 6 years is a long time for a team of Arsenal's stature. We are not looking at this season, we are not looking at one season. So dont compare Arsenal with Chelsea, they are still the EPL defending champions and have won 3 of the last 6 EPL titles. Dont compare your team with Man City or Spurs; these are still below Arsenal, but are slowly on the ascendancy. But remember, soon it could be 10 years...
Maybe you need to look the Liverpool way. In 1996, they may have said, its been 6 years but if we win the EPL, the 6 years will be forgotten. And now look, this is the 21st year of not winning the EPL. Luckily for them, they won other cups as well, but they've not been the same team again.
Maybe at Impunity is right, there comes a time when, in the face of the stiff competition, the coach has to either adjust his philosophy or simply leave. Emirates has the most expensive seats, and what do their fans get for their value? Nothing. Just entertaining football. Heck, even Barca win trophies with their brand of football.
And with City and Spurs on the ascendancy, plus a revitalised Liverpool, the dark days could be ahead...
