Maybe it's not the right attitude but I can understand why that might be the case. The two major points for me, if I was one of his players, is that he doesn't support you (it's always the fault of the players for not adhering to the plan) and that the plan/tactics/strategy is so negative that it doesn't inspire any real positive attitude.
As a consequence, his negativity has made its way into the stands and into this online board. Tragically, there will soon be more fans on this thread than in the stands at Palmerston!
