Jose' returning is still somewhat inconceivable, although.. looking at it from his perspective, he might like the idea of replacing Benitez. Especially after Rafa fucked up his Inter side, and Mourinho's still bitter about what happened with Rafa's Liverpool in the CL during his tenure here. A 'return' rather than a new English club would attract more headlines, which is very much his style. Also, as a force, we're not going anywhere, Roman WILL continue to spend, Jose' won't be able to avoid us like a stepping stone.
What we really need is a technological advancement, so Roman can pull off an ‘Inception‘, get this whole ‘unfinished business’ motive in the forefront of Mourinho’s mind.
