I think that it was your good self that made similar comments when Klopp was announced a the new Liverpool manager.
There were a few, myself included, who thought he was going to be quite the character. You basically informed us that he would be a complete smacked arse when things weren't going his way.
Klopp always was a bad loser - that did not start in the EPL.
He is what we call a Menschenfänger in Germany - somebody that gets the people behind him - atleast the ones that are following his team or neutrals. It might be even easier in Germany where you are for or against Bayern - there is not really a neutral. In England he probably has found the equivalent to Dortmund in Liverpool - not really the underdog but somehow still different to the oil clubs or United.
At the end it always is the same - the referees and FA and the VAR... is always against Liverpool...
