Burnwinter believing is fine, but if there really isn't a difference between our situation right now and City's a week ago, Arsenal supporters aren't the only ones who are being tricked.
The Opta computer thingy had City at 40% a week ago (70% now), while it has us at 18% - so it has us in quite a different situation than what they had City in.
The bookies give you a 5x payout if you bet on Arsenal winning the league, while City had about 2,5x a week ago (1,4 now).
Now, I'm not saying these are entirely precise predictors, but I do think they show that it's not exactly irrational for an Arsenal supporter to be more negative about our chances of winning the league than what City supporters have been while in chasing position.
