Emanuele Giaccherini claims Juventus coach Antonio Conte did not want him to leave for Sunderland this summer.
The 28-year-old left Serie A to join the Premier League club, signing a four-year contract on July 16.
Giaccherini has scored two goals in his opening six appearances, although Sunderland are yet to register a league win this term.
And the winger, who has seen Paolo Di Canio depart the Stadium of Light and be replaced by Gus Poyet, has no regrets over his move.
"I've lived two unforgettable years in Turin and if the decision was up to the coach, I'd have remained at Juventus," he told Radio Mana Sport.
"The club evaluated all the offers that arrived and accepted Sunderland's one. They preferred to let me leave.
"In the Premier League, the football is less technical but much more intense and aggressive.
"Stadiums are always full and the supporters have been absolutely fantastic."
