The former Juventus and Italy boss replaces the outgoing Francesco Calzona, signing a three-year deal at the Stadio Diego Armando Maradona.

Conte returns to the dugout 15 months after leaving Premier League side Tottenham by mutual consent, and will hope to oversee an improvement on a disappointing 2023-2024 season for Napoli.

Scudetto winners the previous year, the Partenopei were unable to launch a genuine title defence, finishing 10th in a campaign where they had three different coaches, firing Rudi Garcia and Walter Mazzarri before Calzona came in.

Conte won three successive Serie A titles between 2012 and 2014 with Juventus, while guiding Inter to the Scudetto three years ago. The former midfielder also led Chelsea to Premier League glory in 2017.

Club president Aurelio De Laurentiis said: "I am very proud that the new coach of Napoli is Antonio Conte. 

"Antonio is a top coach, a leader, with whom I am sure that the necessary refoundation will start after the conclusion of the cycle that led us to win the Scudetto last year after many seasons at the top of Italian football. 

"Today marks the beginning of a new important chapter in the history of Napoli."

Conte, meanwhile, told the club's website: "Napoli is a place of global importance. I'm happy and excited to sit on the Azzurri bench. 

"I can certainly promise one thing: I will do my best for the growth of the team and the club. My commitment, together with that of my staff, will be total."
