Jose's motivational style worked best with a team like Chelsea that was good enough to be in and around the top 4 and a cup run or two but was a step below a league win, molding them in his image was easier than a bunch of guys who had won a WC. The Real/Barca style of managing the football side of operations is also different from being given more freedom in choosing personnel except when he got Sheva dumped on him.
And if Real weren't careful Barcelona was going to leave them behind. I doubt they would have won the league last year with any other manager in world football. Says a lot about Madrid's players that they're beefing when Mourinho when by and large he was loved by his players everywhere else.
