If Liverpool want to win the title, they must win consistently. Liverpool is now only 2 points ahead of Manchester City. Losing a point in a match would also see Liverpool lose top spot in the table. This is why every match now is very important for Liverpool.
Changes in position from first to fifth can still occur because the difference in points is very small. Liverpool is under pressure from Manchester City with a difference of two points, a defeat suffered by Liverpool in the next match makes it lose first position if Manchester City manages to win the match in the same week. This season's EPL competition is more competitive than last season, Tottenham, who is in fifth place, has the same points as Arsenal, who is in fourth place. Arsenal must win the match in Week 21 to stay away from Tottenham and catch up with the points collected by Aston Villa.
Manchester City which is starting to find its best playing form, is trying to reach the top of the standings from Liverpool. The difference of two points with Liverpool makes the competition at the top of the standings even more exciting.
I agree with you. Every team from first to fourth place in the table has a chance to top the points table. Liverpool at the top of the table have collected 45 points from 20 games, and fourth placed Arsenal are now 5 points behind Liverpool. It's not a big gap.
Premier League teams are very strong. So it will not be possible for Liverpool and Manchester City to win every match consistently. It is normal that they will lose points in some matches. So Arsenal and Aston Villa have the potential to top the table. But for this, their overall performance needs to be strengthened. But I think Liverpool and Manchester City will stay in the title fight this season until the end of the season.
