Spurs aren't a problem. Aside from United being a horrible club, what we need is to minimise the number of clubs in the league that are anything like City: infinitely rich and competently run.
Spurs will never be that.
Newcastle are in grave danger of becoming that.
Liverpool look about to go into transition.
Chelsea are several seasons away from feeling the benefits of competent administration.
Out of our current opposition United are the mostly likely to finally exit their banter era and join Newcastle and City in the danger zone. But if it all falls in a heap now then all sorts of wonderful things become possible: Ten Hag sacked, transfer sagas, it's impossible to sell Antony, and more. I want that. My ideal top four would somehow exclude Newcastle as well as United.
