Bettarini pleads innocence
Bettarini was charged on Thursday as part of an ongoing inquiry by the Naples anti-Mafia unit which is investigating allegations of match fixing.
In addition to Bettarini, Modena's Antonio Marasco, Chieti's Giovanni Califano and Como's Alfredo Femiano were also charged in midweek.
But Bettarini insists he has been wrongly implicated in the scandal and wants an immediate opportunity to clear his name.
"I've told my lawyers to ask the judge for me to be heard as soon as possible," said Bettarini.
"I want, either personally or professionally, to show in a short time my complete non-involvement in these situations for which I have been charged.
"These are hypothesis which are absolutely far away from my way of considering sport and loyalty.
"I must underline I have played with the total respect given to me by my club and the supporters."
Sampdoria president Riccardo Garrone also protested the club's innocence in the furore after their match with Modena came under scrutiny.
Garrone said: "We aren't involved and the club are tranquil.
"We are certain also that Bettarini will soon leave this situation and will be able to show his absolute non-involvement in these events."
Only last week, Siena duo Nicola Ventola and Roberto D'Aversa, Catanzaro's Salvatore Ambrosino, Juve Stabia's Vincenzo Onorato and Generoso Rossi were charged.
