SerieA coaching is always a loop, between Allegri, Conte,Gasperini and a few others, no new faces.

And in the low tier teams is the same with other names, for example Davide Nicola who is now on Cremonese but he was before in a lot of low tier teams like Cagliari,Empoli, Salernitana,etc.

The only "new" face is Fabregas in Como but is a super special case in a special team.
