Can' follow you on this one. Pereira, who's one of his former players in Nice, said that Puel certainly played a role in his coming. He's known for making shrewd signings and living up to his reputation until now.
As for the "boring, uninspiring" myth (not directed at you), that's something I'll never understand.
Unless one was in the dressing room or in training sessions, there is just no way to know he really behaves behind the scenes.
Unless one is daft enough to base their opinion on the press conferences and other PR crap.
