I would be more careful with De Zerbi. Potter had a great start with Brighton, and look how the story turned out at Chelsea. It is different to coach a midtable club compared to an elite team. His Sassuolo also wasn't anything extraordinary, not better than the di Francesco team, or the current Dionisi team. Until proven otherwise, I consider this Brighton as a Leicester-lite, one season wonder cinderella story.
I would prefer a coach who has an experience at the highest level. Luiz Enrique, Nagelsmann, or Pochettino would be my go-to move.
