I'm not sure the PL is turning into the SPL. If City win the league it will be by just 2 points. And that's ahead of an Arsenal team who arguably have better future potential than the current City team (although I think Gvardiol will turn into a monster) who are coming to the end of the cycle for some of their players - in addition Arsenal have a wonderkid coming through who is touted as potentially England's most talented player for a generation.
Add Chelsea likely to come good at some stage, eventually Man Utd will stop being stupid, Liverpool with youngsters coming through.
