It is not so much about form maybe when it comes to Chelsea. Some of the games they clearly dominated and won easily, but there were also a couple of games that were super close calls and Chelsea succeeded in the end with a good portion of luck. That luck seems to have left them for now. They are leaving points on the table week after week and City is punishing that brutally.
That enough makes me disappointed (I bet for Chelsea tonight). When Chelsea continues like this or worse in the next game (vs Aston Villa), that is possible for the position (3rd), or maybe the champion shall be far away from Stamford. When I took at the stand, The city is on fire, they are unstoppable to make a champion in the row, just a miracle to stop them.
