I think that's more of a by-product of the modern José, or at least it's become more common as he's aged but again I link that to my original post.Mourinho's good at winning trophies. He's also good at alienating people. If he'd come here like people had wanted him to, it could have gone horribly wrong. He'll probably end up alienating Zlatan and Lukaku and co too.
From numerous accounts, he was well-loved by the majority of his players at Chelsea (originally), Inter and Real as he's keen to develop.
Obviously there'll be exceptions, yet I always took that as a rather ruthless - yet effective - way of motivating or removing players from the camp.
And I don't think it'd be hard to alienate Rom as he's more than happy to do that himself in his never-ending search to inflate his oversized ego.
