If it is related to the points obtained by each team, I think Arsenal still has a chance that is no less than Liverpool and Man City have but when it comes to mentality and how each team deals with pressure in every match, Arsenal might have a problem with that because it's been too long since they last won the Premier League and I think that is also the reason why they failed to get the Premier League Trophy last season. They have the ambition to win the EPL but this ambition has become a heavy burden for them. So in this season, if once again Arsenal still couldn't cope with the pressure, then they will most likely fail again.
The next 2 matches will have a big impact to determine how good the chance of Arsenal to win EPL. If Arsenal can get points in the match against Man City and they succeed to beat Chelsea, I'm still optimistic Chelsea to win EPL title this season. But if they failed to beat Chelsea and missed the points in the match against Man City, I'm starting to forget Chelsea for the candidate of the champion. I'll prefer Liverpool and Man City as the strong candidates for the champion.
Sure, the problem on Arsenal players is always about the winning mentality and the consistency in the second half of the season. The failed to be the champion in the last few seasons was caused by those reasons. I don't know why each the manager of Arsenal, always got difficulty to build a strong mentality on Arsenal players. They actually have many talented players, sadly they have bad mentality.
