For it to all go south on us, all three of Yanited, Liverpool and Chelsea would need to hit title winning type form. If you think about it, that's highly unlikely - not least as they have to play each other.
Our points per game would also have to decline to a level that we have not yet experienced under Unai.
So while there will undoubtedly be some ebb and flow, we really are in the box seats.
This is the thing.
We had a similar dip at the start of the season. Suppose we come out of it for our next game, then maintain the form we had prior to Everton. Suppose Arsenal and Man City have exactly the same form as they've had since the start of the season. In that scenario, we win the league.
It's a rough patch, but if we can come out of it quickly we'll be fine. And as eye_digress says, even if we weren't to - we'd need lower mid table form, and the other 3 to all hit title-winning form, for us to finish out of the top 5 now. Not to say that there's no chance of it happening, but I'm still reasonably confident on that front.
