The Serie A club has been without a manager since Raffaele Palladino's departure in May. Palladino had a successful season at Fiorentina, but his team's performance declined in the latter stages of the season, resulting in a seventh-place finish.
Despite this, Fiorentina managed to secure qualification for the Europa Conference League for the third consecutive season. However, they were eliminated by Real Betis in the semi-finals.
The appointment of Pioli is expected to take place in July, bringing an end to the club's managerial search.
