Agreed that he's going to be at OT one day, but the month of April will determine if he will be back in Madrid next season.
edit: The internal strife has cooled in the media, but that's because the next transfer window is months away. I have no doubt that Mourinho and Valdano still hate each other and will clash again, hard. I really don't think Jose is content at a club where he doesn't have complete control. And there are too many egos at the top to let him be the face of the club.
His brash attitude has pissed off a lot of important people at the club; ones that many people don't even know of, myself included. The political structure of the club would ideally want a lapdog for a manager, but a lapdog that wins trophies. Important part being winning.
I really think Mourinho will consider leaving if he doesn't get the reins fully handed to him in the summer. He should have them, as tools like Valdano can't win jack for the club no matter how much they spend and what they think they know about talent. If Jose can win at least one trophy, beat Barcelona, make a deep run in the CL... He will get what he wants a lot easier. He still may be able to get Perez to give him full power after what we've already done this season, but it'll be a bloody battle unless we win something.
