Secondly, I just think that Mourinho looks out for himself by trying to win games and trophies. He has high expectations. He expects players to be disciplined, to counter attack quickly and to win the physical battles. And when he doesn't have players that can do those things, then both the players who can't play that way and the manager who doesn't win games lose out.
I think this is a pretty good point. His selfishness is absolutely fine when it also benefits everyone else, because as you say, he ultimately wants to win, and that's what the club and the fans want too.
However when that doesn't happen, that's when you see the worst side of him I feel - his me-first attitude suddenly conflicts with what is best for the club/fans when the wins dry up, and he starts making decisions to make a point, and talking sh*t about his own players in his press conferences.
