It is true that in terms of mathematics Arsenal's position is not a comfortable position, they could lose points and not win the Premier League, this is still something that could happen, but you have to take into account the situation of your opponents, for example in the case of city, City's next game will be against liverpool, despite liverpool being an unstable team they already defeated City even when they were worse than they are currently, so there is a great possibility that City will lose points in the next game and on the other hand there is a great possibility that arsenal will get 3 points in the next game, in my opinion arsenal is more stable than City and for that reason I think that arsenal has a better chance of winning the premier league this season
