Mourinho won't go to a place like Newcastle, that team is far below his talents and he would not be paid as high as he used to be. Of course, it could happen if his last stint in united made his reputation so low and made him unwanted so much that he is forced to accept Newcastle and nobody else wants him but I doubt that is the case.

Chelsea would be the ideal scenario for him, the team is not going for championship so he can park the bus and just let them get into Europe next year and that would be enough.
