Sadly the truth. Yet they have to start somewhere, and Wenger has to leave first.
A fresh face at the helm, with fresh tactics and ideas will revitalize their squad, however much. Of course, all these has to begin from their owners, who unfortunately, consistently displays a lack of ambition every season. At every season's end, Stanley Kroenke goes "Oh, we are still in the top 10, it ain't that bad." As much as Wenger hates to admit it, to compete at the top level, you HAVE to spend BIG - both on quality and quantity.
There's a huge power creep in the league, and unfortunately Arsenal's the one being left in the dust.
