Roughly about 10 games per season more now.
Man United around 45 to 55 games in 70s, 55 to 75 in last 20 years.
More games = more goals.
Similar situation in F1. Sport began with 7 races per season. Now at 24 (Imola was cancelled making it 23)
Easier to set records when you have more attempts at it.
Its not as big as you’d think, especially if you weren’t in Europe. Generally true but its around 5 to 10 games more based on my club Man United.
We played 59 games in 76/77 and 54 in 2021/22 season interestingly enough.
