It is interesting to draw parallels with Real Madrid.
Mourinho's man-management style has been largely on the siege mentality, that is incredibly hard to engineer with a club at Real Madrid, who have won nine European Cups, have the entire league virtually engineering around them and Barca and they have a players who have won the World Cup in Casillas like you said.
Now I don't really think the two points I raised are particularly relevant to Chelsea but the third might, it's been a while since Jose's been at Chelsea and since then we have won the Champions League, which was something that Jose failed to do.
Despite saying this I still think there are differences here, at Real Madrid the Spanish World Cup winning contingent lead by the likes of Iker Casillas won two Euros and a World Cup under the stable reign of Luis Aragones and Vicente del Bosque playing a distinct style of play, so in this example they have an example who they can look to where they achieved this success in a very different way to how Jose plays, at Chelsea you don't really have this issue to deal with because of the instability, since Jose Mourinho we have had two successful periods, the first was under Carlo Ancelotti, who despite winning the double did not better anything that Jose Mourinho had done before him, the second was under Roberto di Matteo, now firstly Roberto di Matteo not only was in charge for a pretty short spell but he has also left so he doesn't have to directly succeed him (although truth be told with a figure like Mourinho I think this would be largely irrelevant anyway). Also, di Matteo won the Champions League in a pretty pragmatic way that doesn't really contradict Mourinho at all.
Finally, I think Mourinho is still held in such a special way at Chelsea that the playing group would still be largely in awe of him.
Sorry for being so long-winded.
