Gennaro Gattuso has left Fiorentina just over three weeks after taking over as coach.
The former Italy player was announced as the new coach on May 25, barely 48 hours after he departed Napoli.
Gattuso, who previously managed AC Milan, was set to begin work on July 1.=
After a season in which Giuseppe Iachini was appointed, ousted, replaced by Cesare Prandelli, and then re-installed, Fiorentina finished 13th in Serie A.
Here is the official statement on Fiorentina's website:
ACF Fiorentina and Mister Rino Gattuso, by mutual agreement, have decided not to follow up on the previous agreements and therefore not to start the next football season together.
The Company immediately set to work to identify a technical choice that will guide the Viola team towards the results that Fiorentina and the City of Florence deserve.
The club, which is owned by American businessman Rocco Commisso, and Gattuso have reportedly clashed over transfer policy and resources available for signing new players, according to Italian media.
Former Leicester City and Chelsea manager Claudio Ranieri, ex-Juventus coach Andrea Pirlo, and Frenchman Rudi Garcia have all been linked with the job.
