what amuses me is more how people are taken in by these especially Mourinho's. He does it every week yet they still print/repeat everything he says. He knows how to get the maximum impact and get under everyones skin perfectly. He created a siege mentality at Inter Milan that worked very well...
Maybe thats true but like most post match comments its all hot air that is said in the heat of the moment. Perhaps he hasn't mastered the art of PR but that doesn't mean he believes everything he says but it does leave him open to criticism
When managers go on in the press about this or that, it is purely to do with taking the pressure off the team. A lot of mangers do it yet still people listen and still don't seem to be able to see through it. Journos love it because it gives them good copy and it gives fans something to whine...
