There's already great foreign managers in the EPL, such has been the case for the better part of decade, and while Klopp is a genius on many levels I don't know that his brilliance is such that he'll be able to change the culture of English football anymore than they have. The vast majority of English speaking casuals prefer the "high-paced", "back and forth" football of the EPL and therefore broadcasters do too. He'll bring some strong elements to the league and may even challenge for a title here and there, but I don't foresee either the English hierarchy: City, Chelsea, Arsenal, United... Liverpool-Tottenham, nor the core of its football changing too drastically.
