Man City and Chelsea have been good for the PL. used to just be Arsenal and Utd fighting for title.
Hard to think anyone could do what they did anymore as market saturated with demand with most PL teams affording £20-30m players so problem is which type of player is in their transfer bracket is who would go to a new rich club (Everton) and not go to the big boys.
Man City also done huge amount for area so pretty much a massive positive in terms of investment, developing the area and increasing tax revenue. Shame their stadium was acquired for peanuts when building, or buying at face value, would still be small change to Mansour.
Need to watch out for the Chinese though. Might see a team uproot and play in Beijing at some point ala NFL
