Oscar is far from untouchable, as his treatment in the second half of the season shows (not starting big games, getting pulled at HT in some). I don't even mind him being public -- imo it just reinforces to Ruben that if he can get praised to the high clouds in a press conference, he can get pulled down just as sharply. Keeps him on his toes. I'm not sure that this should be read as Mourinho somehow "not liking him" - let's face it, he has been given chances and hasn't yet taken them and this is a reminder to keep pushing himself, not take things for granted. I think Mourinho knows exactly what he's doing and is looking for a particular reaction that will completely convince him about Ruben's temperament, because the skill is obvious. A sort of a final frontier, if you will.
