Well, it's the problem with player-power, innit?
I wonder if Del Bosque hadn't been cast aside, there was a man perfect for Madrid, where most of his skills come from being a good man-manager, without many tactical considerations. Mourinho tried to surround himself with players who would support him (like he's done at arguably all his clubs), but only alienated the others further.
I just can't see who would be a good replacement. Particularly as it's so hard to work there. Most top managers are quite happy where they are right now, to my knowledge.
PSG's another problem. The league is more even, but if the madrid players don't turn up for Celta, Betis or Getafe, surely they won't for Nice, Rennes or Lorient... Plus the tax on wages is really high as well, haha.
