Ahead of their Derby d’Italia clash against Inter this evening, new evidence in the financial gains case against Juventus has been unearthed, according to Italian media.

As reported in today’s newspaper edition of La Gazzetta dello Sport, the ongoing investigation into whether the Bianconeri has been inflating outgoing transfer costs to balance their books has taken a new turn, with the discovery of a notebook that may hold key information to the case.

The Turin Public Prosecutor’s Office has taken into a position a number of pieces of paperwork as they investigate, and amongst those is reported to be a book belonging to current sporting director Federico Cherubini, in which he recorded the activities of predecessor Fabio Paratici.

Paratici, now at Tottenham Hotspur, is being investigated along with 15 others, and the discovery of the notebook could prove hugely important in establishing whether Juventus had indeed been amending figures between 2019 and 2021.

Cherubini is not under investigation but has been brought into the case due to working in Paratici’s office during the time of the alleged offences.

Investigators also possess an intercepted conversation between Cherubini and Juventus CFO Stefano Bertola in which he urged the Bianconeri to change strategy and focus on homegrown talents to balance the books, rather than resorting to artificial figures.
