Klopp is clearly a fantastic people manager and motivator but I feel comparing him with Pep isn't quite apples with apples as Pep is used to working at big elite superclubs, dealing with egos, imparting his style and getting the results the club expects. Barca, Bayern, City etc. Klopp is used to working at clubs a rung below the elite (Dortmund, Liverpool) where maximising the efforts of a less talented squad vs the massive teams is what is required. Klopp probably doesn't do as well as Pep if he managed City, maybe Pep doesn't do as well at Liverpool.
