Good question! I'm pretty sure it will be this Summer. Rafa would have to have worked miracles to secure his job any longer and so far results have not managed to turn around the negativity that pervades that horrible club.
As far as who it will be... I don't think Mourinho will go back, he is far more likely to go to somewhere like PSG to win a league in a fifth country - mever been done before. Maybe someone like Spalletti? Young, hungry, likes lots of pay, takes no shit, will need to be strong as that team is still transitioning.
What time do you normally go to bed?
