i'm trying to establish a timeline here
2006: 30 year old elkann shits all over his own property just to fuck with moggi whom he could easily fire. collateral damage: serie a loses its appeal and never recovers, all thanks to elkann. rumor says his good friend moratti tried his best to stop him by swiftly placing his own people into key positions of the calciopoli trial, but elkann eventually won and juventus goes down.
2011-2020: elkann keeps destroying juventus. it's the club's most successful league run, under the presidency of an agnelli (elkann's enemy too. andrea snuck into the president's chair without elkann noticing)
2022: elkann realizes that agnelli is the president, creates a case to throw unibrow out
2023: following a 400m and a 300m capital raise, exor board approved an other 200m cash injection, despite elkann's all efforts
there might be some inaccuracies, but the bottom line is that elkann is both the most powerful person in italy and apparently the dumbest one ever too
