Last 10 seasons
Milan 10 87 - +56
Roma 10 83 - +24
Udinese 10 61 - +1
Inter 10 58 - +12
Lazio 10 58 - +12
Parma 9 55 - -2
Juve 9 52 - +15
Samp 8 48 - +5
I can't talk about the last 30,40, 100 seasons, but I can talk about the last 10 and this list presents what was always clear to me.
Milan had 87 penalties in their favor and 31 against them.
Inter had 58 penalties in their favor and 46 against them.
Juve had 52 penalties in their favor and 37 against them.
The difference is too big to be simply explained by "Milan play more attacking football". If that's the case, then why these stats:
Goals scored in the last 10 years:
Inter 64+59+65+68+80+69+70+75+69+27 =
666 goals in last 10 seasons
Juventus 64+67+67+71+83+72+69+55+57+28 =
631 goals in last 10 seasons
Milan 55+65+63+85+57+66+70+60+65+37 =
623 goals in last 10 seasons
If Milan's attacking football is the only reason why they get so many penalties, why did Inter and Juve score more goals overall?
Milan also concede less penalties than Juve and Inter. Is it because their defense is superior to Inter and Juve? In 5 of the last 10 seasons Juve had the best defense. In 3 Inter and Milan had the best defense only in 2 of the last 10 seasons.
Again something doesn't match.
