I believe there is going to be a great change in the club next season, the new players are really trying to prove there worth and I believe the club will fare more better next season. It is beyond the bounds of possibilities for Manchester city to finish first position this season because the difference in point between Manchester city and Liverpool that is topping the premier league is really much. However there focus now should be on how to be among the top four, since the chances of them topping the league this season is out for them, and also there next focus should be on how to win the FA Cup and use that to consolidate there losses this season and prepare fully for next season.
What you're saying may likely happen but their illed performance may persist if things are not properly put in other before the end of this season, the current problem of Manchester City is the overall team and I think it should be properly handled, some players in the club would've to go, this is time for serious actions, we're taking about giving back the team the respect and it's status.
The might achieve top four if the stop acting very unserious aside that I don't see them achieving top four this season, Manchester City current also have a problem in their defense and the finishing, so I think they should work on that for next season, the season is not interesting to me because Manchester City that's a force in the English premier League is not in their peak and everything looks like a joke, Arsenal and Chelsea in the other hand has become a shadow of themselves, as for the FA cup they aren't still sure although there seriousness in the FA cup will determine what'll become of them there.
