I don't think the PL matches will reach their final match play before we begin to know which team will lift the Premier League trophy. It will just be once their 3-4 matches have been played, we can then tell how good or bad their performance has been
Even if 3-4 matches is played, am not expecting any much difference in their points, so I will still say till maybe we are having like 1-2 matches left before we will know who will be winning the premier league this season, as the season is going, Arsenal, Liverpool and Manchester city are not giving up, they are going to fight for the title till the last match is played, this season will be completely different from last season. I just know the winner of this year premier league will be between Arsenal, Liverpool or Manchester, but nobody knows who is really going to win the premier league this season.
I actually think that who will win the Premier League will be determined by the final match because this season the competition is very tight and the three of them have a very small difference in points. Maybe there will be a change in position in the standings after the Man City vs Arsenal match takes place. If Arsenal loses, then Arsenal will remain with 64 points, and it is very likely that Man City will be in second place with 66 points, while Liverpool will be in first place with 67 points. The 3 point difference is not a big gap, and I think if the point difference remains in that range, then the champion will be determined until the final match.
