For people moaning about a United forum's "bad treatment" of poor victim Klopp, and the rather ironic cries of "bitterness", what a load of absolute rubbish. This forum moans about everything, and we are far more insulting to our own manager, former recent managers, as well as most of our players, than to most of our rival managers or players.
Also, there's a reason that Klopp cops a lot more criticism on here than Guardiola, for example. There's genuinely not much to criticize Guardiola for right now. He also doesn't always come across as a raging loon (only sometimes).
If you can't stand that your manager takes criticism on a rival forum, and only want to hear an echo chamber of praise for the man, why would you post on a rival forum?
