what i learned so far, feel free to correct or complete:
fagioli was the first to be mentioned by the whistleblower, one fabrizio corona. he's a convicted felon who already served a sentence for extortion, former paparazzi, enterpreneur (lol), playboy (double lol), so he's a petty wannabe mafioso, and also an interista, so he obviously started with a juventino. if he had an other juventino on his list, we'd know that already. he already called for juve to be relegated, why not. he might have some credible info through his connections with the serbian mafia
as for fagioli, he reported himself to the authorities at the beginning of august. he cooperates with the authorities, he'll probably get banned. according to some rumors, he is reported to be a gambling addict, in that case all he needs now is medical assistance before he completely ruins his life. and there's this:
after fagioli, corona mentioned zaniolo and tonali yesterday. both were questioned by the police, both left the nt consequently, and according to the reports, zaniolo (only him, not tonali) is already under investigation. zaniolo allegedly made bets on roma matches. his defense team says that he only played blackjack and didn't know that the platform he used was illegal.
and there are these, with very little info besides what's posted in these tweets:
