Cheapest adult season ticket at Spurs next season is £865. The following year the over 65 discount will be scrapped for any newly FOC supporters whilst existing FOCs will see their discount reduced to 25% over time until they all stop going / die.
Unfortunately, even more than when clubs could be run by local businessmen owning a few TV rental shops and so on, football is a business first and foremost. Can't afford it? Tough shit, there's plenty who can. Are we really any worse as a club than the others? I'd say probably not.
