Not as simple as that.
You have to factor in those players that City got, where do they end up otherwise? Does Pep end up at Arsenal (he talked about them a lot while at Barca), do they build multiple winning sides under him, do Chelsea and Arsenal win more. Things could go our way as well. There's so many dominoes to fall a different way without that huge financial doping at City, getting and keeping Pep for seven years and counting while his wife lives in Spain.
Those two seasons at second with 74 and 81 points might mean we're still second even third.
In 2014 4th place had 79 points
