Jurgen Klopp is an interesting manager but I do wonder his fit with this Liverpool side. He's got the creative outlets but the squad that Liverpool have aren't going to fit well with an aggressive pressing scheme that Klopp would attempt to implement. It would take some time to get this squad playing the way he would require. It took Klopp 2 full seasons (along with some fortunate prospects + high quality transfers coming through like Goetze, Kagawa, Sahin and Hummels) and a disjointed Bayern Munich to turn Dortmund into title contenders. That climate doesn't exist in this Liverpool side nor is the league so open. The way the English media works, I'm not sure Klopp would have that much time to implement what he wants. With Klopp comes immediate expectations of greatness and with the complexity of his tactical instructions, it could lead to hostility if it doesn't work in the short term. That said, Klopp is a great character and would bring a lot of fun to the PL.
