3 point for a win started in 1981 I believe, so there is probably a flaw in that comparison anyway. We can talk about too much dominance when City have won title number 20. Until then do fuck off.
Don't forget the backpass rule also didn't exist. Liverpool concentrated on getting a lead, then ensuring it was the most boring game of football ever, by playing it back to the keeper, who picked it up, moved a bit, passed to a player, they tried to go forward, passed to the keeper to pickup, rinse and repeat.
English Football in the late 70's and 80's was
generally dire due to that tactic.
It is quite ironic that the 'golden' age of Pep & City, has a similar back pass (but no pick-up), but it leads to more goals, more excitement (for City fans at least), and gives regular trophy wins, due to initial outside investment into the club, making it self sustaining and hopefully should be self perpetuating... there's no difference to City of the 10's/20's and Liverpool of the 70's/80's really - other than (all) the football is better and less monotonous, due to the lack of watching the goalie pick up the ball constantly.
But apparently these complete similarities are not correct, and the game's 'gone'.
