It's worth admitting that Arsenal can be unstable, so an unexpected loss to Manchester City won't change the situation in the table, in my opinion. As for 90+ points, I think that's achievable. Manchester City don't have such difficult opponents in their remaining matches, I would even say easy ones, and it would be too frustrating to lose to them.
there are no easy matches in epl all teams can have a chance to win, this is quite a competitive league it is difficult to say early that they have an easy way in the upcoming matches. I admit that the Manchester City team is highly favored against the opponents they face in the upcoming match. however something else can happen if they get carried away with the current situation which could be bad for them.
one of the things I like about them in every match is scoring goals and scoring goals so no doubt if they continue to do this in future matches I think they will be difficult to beat by their opponents.
Perhaps the unpredictability of the English premier league is what makes it interesting, especially when it's the strongest league, where the competition is terrifying. Assuming the MC win their next game, Arsenal are already 4 points behind, which is a lot in the current situation. That would mean that for Arsenal to win they would need the MC to at least lose and draw. But even under these conditions on goal difference, the MC will still be champions
