I doubt Marotta would get any coach that is not subservient, because by the looks of it he makes all the mercato calls and no sane coach would want an unqualified personal building his squad.
Regardless, I think if Conte were to come back it would be in several years after Marotta has left and that club is more stable, and whatever issues he's had with the club would die down. Personally I wouldn't welcome him back.
