City's next league games:
vs West Ham
@ Manchester United
They also have a game against Arsenal but not sure when they are playing it.
I think they'll lose at least 3 points from those games, so for me, 4 maybe 5 wins from the next 6 will do it. If I have to say, I think 12 points will do it.
Like HR said above it's done, just a matter of time.
