Everything you said above is your opinion, not a matter of fact. Klopp is neither dogmatic or obsessed with himself like Wenger is. He has won two league titles in a row which Wenger hasn't done. He has lost some fantastic players, most of whom are irreplaceable, so you can hardly blame him for that. How many players as good as Lewandowski can you name that are available. Klopp may not be the best, nor the only option out there, but I would take him in a heartbeat over the old busted flush we now have.
But I agree we need to conduct a search for a replacement diligently. We will get 4th, Im pretty sure. Its a crap league and we usually get there in the end.
