Ronaldo has the same pattern - look at Barcelona's goals per season before and after him:
94/95: 60
95/96: 72
96/97: 102
97/98: 78
98/99: 87
And at Inter his first campaign was their highest scoring season since 1965 when they were the best team in Europe. And that's despite as

I thought it was pretty obvious that the superteams are racking up more points and goals nowadays.
It's no coincidence that the highest scoring individual seasons in the last 50 years across all the major leagues just happen to be in the last decade or so.
Serie A - 2015/16 Higuain / 2019/20 Immobile - 36 goals (yet the highest Ronaldo and Van Basten could get was 25)
La Liga - 2011/12 Messi - 50 goals
Bundesliga - 2020/21 Lewandowski - 41 goals
EPL - 2022/23 Haaland - 35+ goals
Ligue Un - 2015/16 Ibrahimovic - 38 goals
It's no coincidence that the highest points-scoring club campaigns in the last 50 years across the major leagues happen to be in the last decade or so (factors in best points-per-game rate):
Serie A - 2013/14 Juventus - 102 points
La Liga - 2011/12 and 2012/13 Barcelona and Real - 100 points
Bundesliga - 2012/13 Bayern - 91 points
EPL - 2017/18 Man City - 100 points
Ligue Un - 2015/16 PSG - 96 points
