I think the point difference for now is still 6 points and there is no certainty that Manchester City will win full points in the upcoming match even though they are superior on paper.
arsenal can still keep the distance to stay on top of the standings if they are really ambitious to win the title this season.
Arsenal next opponents are also quite tough in the upcoming matches such as Manchester city, Newcastle United and Chelsea so they have to make the most of their consistency in the title hunt this season.
For Manchester City, Arsenal draw gives them the opportunity to reduce the lag in the upcoming match.
Being held to a draw by Liverpool is a big loss for Arsenal. Even though the points only increased by one, it was clearly not a satisfactory result. In other words, Man City has the opportunity to catch points easily. The current difference proves that once again Arsenal loses one match, meaning Man City can be above them. It is possible for Man City to take advantage of the opportunities in sight. So 1 match will mean a lot to Man City and Arsenal and the match against Liverpool requires Arsenal to focus on winning the next game.
