Prosecutors investigating corruption in Italian football have requested the indictment of former Juventus director Luciano Moggi and seven other people.
Moggi was banned for five years at fined after the July probe
Italian news agencies are reporting that they are accused of conspiring to control transfers by intimidating players to sign for agency GEA World.
GEA - a sports agency - is run by Moggi's son, Alessandro, while Marcello Lippi's son David also faces charges.
Prosecutors said the indimidation often included threats of violence.
The probe is one of several criminal investigations into corruption in Italian football, including sports fraud, illegal betting and false bookkeeping.
Luciano Moggi was banned from football for five years by a sports court in July for influencing the outcome of matches.
As part of the trial, Juventus were stripped of its last two Serie A titles and relegated to Serie B with a nine-point penalty.
Four other Serie A clubs - AC Milan, Fiorentina, Lazio and Reggina - were forced to begin the season with point penalties for their roles in the match-fixing scandal.
GEA World handles more transfers in Italy than any other management company and in 2005 had more than 200 players on its books, according to Italian newspaper Corriere Della Sera.
