Although the club has not unveiled dealtails, but the Italian news agency Adnkronos reported that former Chelsea and Juventus manager had a two -year contract, with an option for a third season.
Sarri resigned in March 2024 after almost three years, after seventh place in 2023-24, against the second place of the previous season.
“Maurizio Sarri has returned. His return is a choice of heart, conviction and vision,” said club president Claudio Lotito in a statement.
“With him we want to resume a path too quickly, aware that together we can bring back enthusiasm, identity and ambition. Welcome back to your house, commander.”
