The Juventus Coach risks a 15-month ban for failing to alert authorities to a potential fix while he was at Siena in 2010-11, although he is fighting the charges and it's reported could be suspended for 10 months.
"The group of lawyers is strengthening to prove that Conte didn't do anything," Moggi told Radio Kiss Kiss.
Moggi is a familiar figure to Juve and the courts, as he was considered the 'mastermind' behind the Calciopoli scandal that saw the Bianconeri stripped of two titles and demoted to Serie B in 2006.
"Conte is a man who wants to win the games and has nothing to do with the betting systems.
"I have known Antonio for 10 years and the very thought of him fixing games is out of the question.
"Giving a platform to someone who admits he fixed matches while another 13-odd teammates say it wasn't true seems typical of the current Federation."
