Player Valuation: £90m
They're not that fantastically run, when their reluctance to spend in the transfer market will cost them £20m+ next season when/if they fail to qualify for the CL.
Spurs are a far better example of a well-run club that invests in its' playing staff at the appropriate times to support the manager and kick the team on to the next level.
Arsenal have £154 million in the bank, all their debt is on fixed-term and is at a low interest rate, they made £95 million in matchday revenues and £52 million in commercial revenues during the same period, and they made a profit of £30 million after tax in 2011-12. They are a much better run business than Spurs.
Also the reluctance to spend money on the squad is almost certainly down to their manager.
