Bit puzzled by that one, frankly. Genuine question: could you make your criteria for that one explicit? Because whether its trophies (a dubious criterion, in itself), crowds (again, can be contested) or any other, I'm having difficulty seeing how Spurs are as ‘big’ — whatever that may mean — as Arsenal. Or that they ever have been, except for the relatively short period at the beginning of the sixties when many people felt the Spurs of Danny Blanchflower were playing the finest football in the land.
It's one of the reasons why I find Spurs supporters so difficult to bear. I find some of them incredibly gobby (not all). I was a nipper when they were last champions! Literally.
Just a little touch of humility would be so refreshing. Not holding my breath though.
