Someone who has his own ways of handling things that's Mourinho for you and as the club management is concern they need to do things the way he wants like both parties need to understand each other and I feel they never understood Mourinho that's why things are the way they are, sometimes he fight for the good of the club not always saying the negative side I think, at first I thought it was because they didn't qualify for the champions league but is not the case, is something big that we might not know until he comes and talk about it, like you said the sacking has been coming and I believe that Mourinho knows this would happen.
Some of these clubs you made mentioned of I think I'll have to say some of the clubs are at fault, is not always Mourinho who's at fault, the thing is before you sign a manager as Mourinho you have to be ready for anything that comes from him after all his reputation speaks for him and he's a good coach, aside from that fact he knows how to do things his way without letting the management know I don't see anything wrong with him.
