As others have pointed out, the difference in GATE RECEIPTS ALONE is 10 times that which you quote. Then there is corporate hospitality (I do understand that you would not know about this if you only ever visit Nottarf Krap), other additional incomes that a modern stadium brings (again, I forgive you for not knowing about these), other monies spent by fans on a matchday, etc, etc.
So the difference is quite a huge one. I bet you wish Poopey even had the 5.5m to spend on players (legitimately, for a change) this close season.
