Im sure the correlation to money and results goes all the way back. Remember reading that the early 1900’s shows the same thing. Sort of explains why its always cities which have the best team, towns and villages didn’t have as many fans so couldn’t compete in monetary terms in the early days.

In a more general reply, Buying the best player doesn’t guarantee success. Man Utd have bought a lot of seriously good players. Its the whole club that makes a team competitive. Man city are very well run and their facilities and academy help too. Lazy to just insinuate money is the only reason.
