When you actually think about the whole certainty around top 4 is random. For example, take City & Chelsea, a short while ago Chelsea and City may as well have been Villa and Forrest, defo were not Big 4 territory, they are new realitvely. So from that point of view say Burnley and Sheff Utd are taken over in five years time by oil rich foreigners we are into what then the big 8.
Blackburn to they were the a City and Chelsea of the time just before and crashed the CL.
We move into a new ground, our turnover jumps by 50% we qualify, big 9? Wolves taken over a couple a years ago, would we be surprised if they have a good season and get top 4 next season, over sat Arsenal or Spurs, I wouldn’t be.
I just think based on past history, recent developments and the nature of change in football it’s dynamic. Actually City and Chelsea are prime examples of how dynamic it can be, they were just run of the mill rank and file clubs until relatively recently in the history of football. In fact we for example are far more constant as a football club over football history.
