Yes, thats basically a rookie coach that just started out and is getting his first stab at a top club.
Havent actually checked, but my feeling is all the other coaches in Serie A besides Palladino and de Rossi have 10+ years experience on the job, yet Motta is rumored to land just behind Inzaghi who's at 5.5m.
This feels like another instance were Juventus is paying more just because we're Juventus, if he signed for Napoli or Milan he'd probably be on 2-3m or smth.
