How so? City kicking Liverpool out of the top four is change yes, but I see no "football is far better for it" effect. All that's changed is we're one of the old boys now, if not yet respected and loved by others at the top table. This season Chelsea imploding leaves another spot open in the top four and Utd slipping down the league might well result in another slot opening up, but their demise is not directly linked to our rise. Leicester winning the league, now that would be seismic, but the rise of City as a positive change for the league? I can't see it.
We kid ourselves if we think we've changed football for the better, we've done nothing of the sort, we've just changed our football for the better. Maybe the other clubs might have to invest more in their football infrastructure, academies and so on to keep up with us, but apart from that we've not shaken up much in the Premier League beyond going from everyone's second favourite team to being one of the most hated and for that you can blame the media.
