I hope that Arsenal will overtake City and we will find out who will take the title in the fight between Asenal and Liverpool, but I must admit that 5 points is a lot for teams that are fighting for the title. In the Premier League, the champion usually dominates very strongly and very often the percentage of points scored is more than 80%. It turns out that on average the title holder scores 2.4 points per game. To “catch up” a gap of 5 points, you need to play at the maximum (win) 5/0.6 = 8.3 games. It's not so easy in the Premier League.
It is difficult to catch up points in Premier League matches even though it is only 5 points away, Arsenal still have to win strongly and Liverpool or Man City make mistakes with their defeats.
Suppose in this season's title battle between others is Arsenal vs Liverpool then here will choose Liverpool with a clearer opportunity, usually Arsenal always get problems towards the end of the season or say performance decreases due to defeat.
You have to calculate their winning percentage, so now you know enough.

Anyway, Arsenal's task in the Premier League is difficult, we never imagined it but maybe the battle will belong to Arsenal.
The battle is really going to be a tough one because I believe Arsenal have not given up on the tittle race,and if they should keep that hope alive,they must go on to win the remaining of their fixtures and not dropping points again,else,it will be over,it will be fighting for top four again this season.Arteta is the reason why Arsenal dropped some vital points that they dropped this season,because he loves gambling with some games by keeping the wrong players on the pitch for a long period of time.There are times when Hervetz was criticised because of his poor performance,but Arteta kept on playing him.Arsrnal have a very good squad,but managing them to get results is another important thing that needs to be done.
