It could be that the decider of the league won't be between these 3 teams, what I mean is that they can't beat each other to decide who will win the league title (Liverpool can't win Manchester City and Arsenal can't defeat City). Liverpool played a draw against Man City and Arsenal can as well repeat the same thing and the 3 teams will have to look for elsewhere to get there 3 point.
Arsenal can be at the top till the end of the season only if they repeat what they did last season by slipping off the top, I don't see any threat coming the Gunners way this time around, Manchester City people are tipping to be the favorite to win the league doesn't have enough goals this season compare to last campaign which means this guys are struggling to meet up, as for Liverpool they will definitely drop point that might see them finishing 3rd if care is not taken.
Liverpool has a big chance to emerge as champions when Manchester City draws with Arsenal. Determining the title is still quite difficult to predict because the difference in points between the three clubs is still quite close. Liverpool can take advantage when Manchester City draws with Arsenal, but the chances of the match ending in a draw are still quite difficult, because the match will take place at Manchester City's home ground. Arsenal can top the standings if they beat Manchester City and vice versa, Manchester City can be in second place if they beat Arsenal.
In this scenario, Liverpool really benefits because they can take first place in the standings if the match ends in a draw. I am more confident that Liverpool and Manchester City will come out as champion candidates because both of them have a much bigger chance than Arsenal.
This scenario hits differently to Liverpool players and fans if the Arsenal and Man City match gets drawn on next week's Sunday fixture. The top 3 teams are in a race for the EPL title and every match for every team is very important a single draw benefits other teams to make sure to secure the Top position in the EPL table.
