Why the assumption you will start firing? Or is it just blind hope? You might have a hot streak at some point but for me this is Arsenal's level. There's half a dozen games you could have been looking at different results. Credit where it's due for pulling them out of the bag but it's not sustainable and will catch you out enough times over the season.
Then look at city, notoriously slow starters. Today we had 5 midfield options unavailable to us. We went to arsenal with similar problems. The best midfielder on the planet has barely kicked a ball for us, there's a multitude of reasons to believe city will start firing come the turn of the year.
Most city fans believe the dippers to be our biggest threat because they have a higher ceiling than arsenal. They've got their own weaknesses and it could fall apart for them like last season(let's hope) but crucially, they don't have the mental fragility arsenal possess.
It's embedded into your club, a manager whose head explodes at every opportunity, players who follow suit and haven't done it before and a fanbase that swing from monumental positive overreaction to monumental negative overreaction on a weekly basis.
