According to Italian reports, after Grosso's dismissal, Fiorentina will appoint Vanoli as their new head coach.

Di Marzio stated that Fiorentina have already chosen Vanoli to replace Grosso, and the two sides are finalizing the last details of the manager's return.
Fiorentina believe that Vanoli, who has previously coached Torino and was already in charge of Fiorentina last season, can be the right candidate to help the team emerge from its current difficult situation.
Fiorentina have had a very difficult start to the season. In their first three matches, the team suffered three consecutive defeats, conceded nine goals and scored only one. Although the club performed well in the transfer market by signing players such as Dragusin, Mastantuono and Beto, the team has still been unable to find its form, and its performances in the opening matches have been disappointing.
Vanoli's task will be to reunite the squad and improve the internal environment of the club, helping the team raise its league position as soon as possible.
