I think they are going to win all their home games, they already have United, Everton, Spurs and Arsenal out of the way and disposed of all of them with ease, I don't think Liverpool or Chelsea will pose much of a threat although they might drop points to either, rest of the league will get their asses spanked at Etihad. Away from home they've been dodgy but they are bound to improve, they've had some positive signs lately.
49 out of 63 for a team of their quality isn't out of question. 11 of them are home games so there's 33 points if my assumption is correct, only need 16 out of remaining 10 games to reach the target of 84 points.
