Man City can always beat Arsenal but then last week Arsenal managed to beat Man City. In my opinion, the same thing could happen in the Chelsea vs Arsenal match. That is, Arsenal can always beat Chelsea, but it could be that in the next match it will be Chelsea who can beat Arsenal. Although statistically I also agree that Arsenal will actually be much more favored. Chelsea have not found their best performance because Chelsea actually does not have a mainstay striker at the moment. Their consistency is also questionable. So it is not surprising that Arsenal will be favored by many people.
The problem is that currently Chelsea is in a bad situation. If you look at the statistics, this is something that has happened several times in previous seasons where Chelsea were often able to win matches against Arsenal. However, in the current situation at Chelsea, I see that there is almost no chance for them to win. Arsenal have not been defeated and Chelsea have suffered 3 defeats. Chelsea is currently the worst in previous seasons. I think it will be an easy win for Arsenal.
