Not a single Spurs supporter on here is arguing that Spurs have a richer history, so I still don't understand why you keep bringing it up.
But it's 2019 now. Spurs have been gaining a lot of ground over the past decade and are a top ten club in current day. I'd call that a big club. You can't keep living in denial.
In terms of Arsenal Vs Spurs I'd argue that Spurs have been the better team for the past three years. That because of Spurs rapid progression and Arsenal's mismanagement as of late. I think the league results and european results prove that.
But I wouldn't be the least surprised if we got passed soon again sadly. I was rather impressed by Arsenals transfer business this summer and I think they have the best academy crop in England. Whilst I think Spurs near future is extremely unpredictable.
I agree with most of what you said, and I also think we have been worse for three seasons now, although I do expect that to change very soon. I dont think you have progressed either, you have regressed over a couple of seasons now.
I don’t think you are not a top 10 club, top 15 is probably more reasonable. And without the fans and history, you can’t be a big club, titles, honours and fans are what make a big club. Looking at club size, you are not even a top 10 club in England. City and PSG are not big clubs, not even close to it, even though they are top 10 clubs comfortably.
