The problem is, as has been mentioned before, is that people think press conferences are robust exchanges of views. They are not. They are totally controlled, obligatory PR events.
If you ask a question a manager doesn’t want to answer, he won’t answer it. It’s that simple.
If you start ranting after a defeat (which is what people really want when they come out with the disingenuous ‘difficult questions’ line) you will literally be ignored, it will be clipped by opponents of the club and fans of other clubs will piss themselves laughing at it.
I very rarely go to press conferences because they are generally the same thing. All that comes out of a presser of note is injuries/squad.
These threads should be titled ‘I’m in the huff about our form and upset that nobody has told the manager I hate player X and Y’.
