I think ADL is too smart for that to ever happen. He's the one that saved the club from bankrupcy in 2004 with the club in Serie C paying next to nothing and has made them a powerhouse . Since returning to Serie A in 2007/08 Napoli has won 2 scudetti, 3 Coppa Italias, made the Champions' League 10 times and Europa League 5. (yes some of them after being out of CL).
We can only dream of achieving those results in that time-span, all done we healthy finances, no borrowing, and one owner only.
we've had 4 since ADL at Napoli with one forced to sell, one failing because unable to pay his debts, and the last with disastrous sporting results. Napoli has just had one terrible season, but has been able to afford and/or develop champions like Cavani, Higuain, Osimhen, Mertens, Hamsik, Kvara, Koulibaly, Insigne, Jorginho, Allan, and many others.
I would be happy as hell to swap ADL for RedBird as our owner, but for some reason Napoli keeps getting under-valued and under-estimated by many. So, no, Napoli is at no risk of being bankrupt because they sell players at huge plusvalenze while replacing them with equal if not better players. They can afford to spend 200 million in the transfer market with the sales of Kvara and Osimhen among others, afford 7 million salary for KDB and 8 for Conte who gets a raise from 6.5, while we cheap out with Fonseca and Conceicao.
I'm a huge Milan fan but I like to be objective when I rate the strenght of our rivals.
