That doesn't say Arsenal received funding at all, its ambiguous at best and likely refers to negotiating that some of our flats were designed to be cheap, like houses for teachers and the like(forget what that scheme is called).
AFAIK we received little to no funding and had to buy out and move the properties already on the site, neither of which were cheap to move.
Arsenal definately paid out at least 7.5mil for upgrades to the local stations though fairly sure the amounts increased later on.
Don't see what the issue is tbh. Tottenham is a poor area and Spurs are the best thing to happen to it. Why should it be purely down to a football team to fund regenerating the area, isn't that what public funding is for?
Things that can help build up the local area are one thing, the ability to bring in 60k screaming fans in one go is pretty exclusive to the stadium, as with Highbury/Emirates, other than the football theres zero other reason for stations/roads/public transport that can put 60k people in the stadium in such a short space of time, therefore we helped pay to make the station work with those kinds of numbers...... as should Spurs.
Benefits everyone.. maybe just maybe get extra funding, only useful for Spurs to make profits, they should pay for it, like we did.
