It's a short term thing though.
Liverpool, Arsenal and Spurs can't compete financially long term. Spurs have been elevated by Pochettino but that's short term, it'll go when he does. Arsenal's board will never invest enough to out do the big spenders and Liverpool similar.
So then you've got Mourinho and Conte, both one bad season away from resigning, and the new coach coming in will need to rebuild.
If we were to win, for example, the next 2 league seasons, Mourinho, Conte, Wenger & Pochettino would be gone. Suddenly there's not so many great coaches and suddenly we've got quite a lot more money than all of them.
