I've said it loads of times before, for me Mourinho seems to do something, he can create a short term winning mentality, but at some stage EVERY team loses, and starts to do worse, and his teams seem completely unable to deal with that. Take a team almost at the top anyway, work some mental mumbo jumbo to give them uber confidence, then win for a couple years, then they fall to pieces.
Real even playing basically all the same players just aren't a patch on last year. City look worse than last year, but not THAT much worse and are still getting results, the amount by which Real has declined is insane, and they are dropping points constantly, are already looking like they could struggle for second rather than first this season.
Their play is disjointed, just about everyone looks unhappy, Mourinho is a **** in general but always was when they were winning also(eye gouging and his kick on Cesc who was down after a terrible tackle by Marcello, I've NEVER seen a manager do anything like either of these, both horrendously unprofessional), Ronaldo is still scoring and making chances but doesn't look at his best. Ozil/Di Maria, Modric, Khedira, look pretty poor. The team just doesn't seem right, same way Chelsea had a great team but didn't seem right before he left, and the same way Inter had a great team but didn't seem right in the season after he left.
Short term good, then his teams fall apart, and he seems to do pretty well to get out quick with success before a team can fall apart. Financially he left Inter in a mess and spent like a complete idiot at Chelsea, and has spent very poorly at Real.
Falcao just almost scored an awesome header as I was typing, off the inside of the post and out, he really is just awesome, ridiculous power.
