Cannot overstate how much more competitive it was back then. 7 different champions in successive seasons from '66 to '72 :-
Liverpool, Rags, City, Leeds, Everton, Arsenal, Derby.
Saying that, City should have won it in 1972 regardless of signing Marsh and probably would have won it in 1977 with a fit Colin Bell available.
Yes everything was more equal back then. 1972 left me gutted as a kid, I think we were clear at the top for a while. We fell away over Easter and in particular getting beat 2-1 by Stoke at home when Gordon Banks put in one of the best goalkeeping displays I have ever seen. Without him we would have won that game 7-2 we absolutely pulverised Stoke.
We should have won it in 1977/8 as well, we were the better side. A bloody icy pitch and that bloody Fairclough meant we drew with Liverpool, them scoring in the last few minutes.
