I used to love watching Dortmund whenever I got a chance, the atmosphere at home was electric, and they played fantastic football. I do think Klopp is a great manager, just that the quality of player at Liverpool is just not good enough. Realistically, Coutinho is the only real genuine world class player in the squad, whereas at BD he had 4/5 of that kind.
I don't watch a lot of premiership football, as I find it over hyped by sky, when it's plainly obvious that la ligue is the best in the world! But I will watch Arsenal (have a little grá for them) and Liverpool or Chelsea, for obvious reasons. Even city are poor to watch, their flair seems curtailed oddly enough under Pep.
I guess I'm trying to say, Klopp will most likely succeed, he just needs more transfer windows and 2/3 more real quality players. I think Pool would be mad to get rid!
