Luciano Moggi could face a prison sentence of almost six years, announced prosecutors in the Calciopoli 2 trial.
The civil trial has been going on in Naples for several months and brought to light new evidence compared to the 2006 sporting investigation.
Former Juventus director general Moggi remains at the centre of the allegations of wrong-doing and public prosecutors have concluded their part in the trial by demanding five years and eight months.
Former refereeing designators Pierluigi Pairetto (four years and six months) and Paolo Bergamo (five years) were also the most heavily penalised by prosecutors Stefano Capuano and Giuseppe Narducci.
Ex-FIGC Vice-President Innocenzo Mazzini (four years), former referee Massimo De Santis (three years), Fiorentina owners Andrea Della Valle (one year and 10 months) and Diego Della Valle (two years), ex-Messina director of sport Mariano Fabiani (three years and eight months), Reggina President Lillo Foti (two years), Lazio President Claudio Lotito (one year and 10 months) and ex-Milan director Leonardo Meani (one year and six months) were also involved.
Some former referees have been caught up in the trial and the prosecutors are demanding these sentences:
Paolo Bertini (two years and four months), Salvatore Racalbuto (two years and two months), Antonio Dattilo (one year and eight months) and Pasquale Rodomonti (one year). Journalist Ignazio Scardina also faces a potential sentence of one year and two months.
It should be noted that the Italian law can convict people with long sentences and yet never see them inside prison, while there are also numerous levels of appeal to go through.
From Tuesday June 7, the defence will take to the court to make its conclusions and recommendations.
The trial is expected to end by July 19, but the entire scenario could be wiped and start from scratch if the legal challenge against judge Teresa Casoria is upheld.
