The financial mismanagement at Arsenal for the past 15 years is going to be a massive story over the next couple of years.
Circa 2005 they were one of the most popular clubs in the world, with globally recognised superstars and a huge African fanbase, and they completely failed to cash in. Their lack of commercial growth as pointed out by Swiss Ramble is absolutely scandalous when you consider Spurs have caught up to them after 3 decent seasons with zero silverware.
They are now being financially outgunned by the likes of Leicester and Watford, let alone Spurs and modern Chelsea, two sides which are refusing to make losses or borrow money.
Wenger spent a decade being told he was a financial genius and his hard work was setting the club up for a bright future at the top of the game, and instead they'll likely be condemned to the mid-table before he's 75.
And in the most competitive football market in the world, with 4 or 5 London Premier League teams at any one time and the most expensive season ticket prices in world football, that stadium that was supposed to take them to the promised land will not be full for long - they saw that already during Wenger's final season when attendances were shocking.
