Speaking to Tuttomercatoweb, the 56-year-old Italian spoke in terms that suggested a farewell rather than a continuation, praising president Aurelio De Laurentiis while indicating the decision has already been communicated privately.
"The president has known my thoughts for a month already. I have a friendly rapport with him. I arrived at Napoli during an extremely difficult period, after the team had finished tenth, with a feeling of depression at the club."
He pointed to a promise he made when he arrived and indicated he has kept his side of the bargain.
"I had promised that in the moment my experience at Napoli was over, I would leave behind a solid and ambitious group, capable of fighting and always causing problems for opponents."
Conte also said De Laurentiis has always shown him trust regardless of what comes next, and expressed personal gratitude toward the owner.
"He always put his faith in me, regardless of what will happen next year. I will always be grateful to him for having been given the opportunity to coach a club like Napoli."
Conte is under contract until 2027 but has a clause that allows him to leave for the Italy national team coaching role. That job is expected to become available following FIGC presidential elections scheduled for June 22. Napoli have been planning for next season on the assumption that a summit between Conte and De Laurentiis would clarify the position, but Sunday's comments suggest the outcome may already be decided.
