There's also a gap between "no managerial experience in the Premier League" and "no exposure to the British football culture and ethos" that a lot of the names above (Kompany, Alonso, Postecoglu, Carrick) fall into.I just don’t see why it needs to be someone with prior EPL experience.
Plenty of managers have come into the league and been (relatively) successful without prior experience. I’m not sure I want an unsuccessful retread on the basis of experience.
When those successful outside managers talk about their experiences making that transition, it's always that cultural stuff they mention as opposed to getting up to the speed of the league.
