with Arsenal's good performance this can make them at the top of the rankings, but the points they have are still not safe, Manchester City is still a threat to Aarsenal, because with their narrow points difference it could allow Manchester City to overtake their points and returned to its top ranking. Also I think with Manchester City's next match that will take place I think they can still catch up with their points which are slightly different from Arsenal so there is a possibility that Manchester City can overtake Arsenal.
Of course, Manchester City's performance cannot be underestimated, Arsenal must be prepared for their ranking which might be shifted by Manchester City, which is performing well.
Manchester City have one game more left than Arsenal at the moment, so Manchester City only need a win in each of their games to win the trophy even though Arsenal are unbeaten in their remaining games as well, the points difference owned by Arsenal over Manchester City at this time is certainly useless if Manchester City does not suffer a defeat or at least one draw in the remaining matches, If Manchester City loses one game, of course, Arsenal is still 1 point at the top of the table, as well as if Manchester City get a draw in the rest of their matches, of course Arsenal have a greater chance of winning because they have a better goal difference than Manchester City at this time.
But Arsenal main problem at the moment is to expect Manchester City which seems to be impossible to lose to teams like Tottenham, Fulham, Westham and Wolves, indeed Arsenal still have hope to win the Premier League this seasons, so Arsenal should be more focused on winning the remaining games they have this season other than hoping that luck might be in their favor to be able to end the season with a championship even though it seems a bit It's hard in my opinion.
