Thats all true, although of course leaves you incredibly vulnerable to Pochettino leaving, but I think you're vastly downplaying the importance of money.
Wages spent is a pretty accurate predictor of success in the Premier League. This article is out of date, and there are high profile exceptions since including you, but the rule still is holding true enough.

The most reliable source I can find for wage spend is from last year.
http://www.espnfc.co.uk/blog/tactic...-dominance-is-down-to-wages-but-can-be-broken You're sixth and a significant way from fifth so I doubt you've made the gap up. Whilst this is obviously a good thing whilst you're overachieving, its hard to shake off the idea that eventually you're either going to have to find the money to pay the players what they're worth, or regress to the norm which will probably happen as a result of players leaving.
I know it sounds patronising, but Spurs aren't one of the financial big boys and until they are, whilst deserving a lot of credit for what they have achieved, I do think Spurs fans ardent rejection of the possibility that any of their players might want to go to 'worse' clubs, be they United, City, or whoever strikes a little bit hollow. Of course, you're in a fantastically good position in terms of contracts, and are very well run. But I can't help shake the feeling that everything is, for the time being at least, built a bit on a house of cards.
