I think we need to look specifically at the commercial revenue instead of the full revenue profile, as Ronaldo has a very indirect and probably also insignificant effect on our Matchday revenue and Broadcast revenue.
Juve's commercial revenue per Deloitte:
15/16 101.7m
16/17 114.4m
17/18 143.3m
18/19 185.6m
19/20 188.9m
With how things were going prior to Ronaldo, we can asusme that without him we're probably not making that jump up to 185m in 18/19, but surely we're not that far off either from those numbers, our commercial revenue was already steadily growing before signing CR7. With Covid kicking in, I think it's rather clear that Ronaldo definitely doesn't finance himself now and probably won't in the future as well, I'd say we can attribute anything between 10-20m / year as extra revenue that he brought in.
