It's a romantic idea that we'd get the Mourinho during his Porto/Chelsea days, but that was more than 20 years ago now and football has changed so much.
I dont think he's been a failure in recent years I just don't see a manager who's adapted to modern football and he's as stubborn as Dyche.
But if you had to decide between them both I'd go with the guy who's won trophies and who has a personality.
