People are vastly overreacting. City are still the best footballing side in the league, they're still one of the favorites to win the title,
and if you really want to argue anything based on today's game, it can only be that Guardiola has an edge over other managers. City thoroughly exposed Chelsea. The latter were neither better nor more clever or ruthless, they simply had an awful lot of luck on their side, they deserved nothing out of that game.
Prediction: Chelsea will drop out of the title race come spring, and City will fight it out with Liverpool.
@Kostur: You have to go back. (to /sp/, that is)
