Premier League is indeed currently the most stacked league not only about the players but also top quality coaches flocking in. Yes, we lost Tuchel, Hassenhut, & Gerrard but we've got Unai Emery of Aston Villa & Julen Lopetegui of Wolves.
If Alexander Isak becomes healthy again, I suspect Newcastle can become a Champions League contender in the coming years on top of Premier League title contenders.
