Mario Giuffredi announced in an interview with Radio Kiss Kiss Napoli that Marianucci has renewed his contract with Napoli until 2023.

The agent also mentioned that Allegri highly values the defender: "Allegri really appreciates him." The agent then talked about how the player's physical issues in recent weeks affected the process: "It was a shame about that small injury, because he had already become an undisputed starter at that time."
The renewal until 2032 undoubtedly sends a very clear signal: Marianucci remains at the core of Napoli's technical plans, and the club has chosen to keep him firmly in place for the coming seasons.
