The Viola certainly had a dismal start to the campaign, as they were crushed 4-0 by Roma, 3-0 at home by newly promoted Frosinone, and 2-1 at home by Torino on Saturday.
That proved to be the final straw, although there were also reports of tension growing between director Paratici and the coach.
Fiorentina have sacked Grosso
Grosso had only been given the job in the summer after an impressive couple of campaigns on the Sassuolo bench, and was rewarded with heavy investments on the transfer market.
However, aside from a 4-1 Coppa Italia victory over Benevento, the results were dire with three defeats out of three in Serie A.
It is the second season in a row where the Tuscans have sacked their coach in the first few weeks of the campaign, as Stefano Pioli had also been axed in November 2025 after 14 competitive outings.
It’s not clear who could replace Grosso, but the search is on ahead of their trip to Venezia on Friday September 11.
