inter is lower than i reported it seems though - Swiss Ramble reported something around 500m, dunno from where they took that 800 in Il Gornale.
from the balance sheet i guess
~500m is their net debt probably, i didn't check. debt can be reported and calculated in multiple ways, so both numbers can be factual. depends on the methodology. juve also has a net financial debt of ~340m which include money the club owes to bondholders, banks or factoring companies, but if you include like money due because of transfers and agent fees, the debt is 425m
you should check inda's financial report or that il giornale article (or that blog post by luca marotta) for more info i guess
