It's a fact that things are like that for Chelsea, it's a bit sad because they've lost a lot of points , and losing points in the PL is quite worrying, because any team can run over you if they fall, if not, you have to ask City, in the case of Arsenal, they're a very good team, but they're not consistent, they're not Capable of holding out for a long time while winning, and that's something that Liverpool does have, that's why they're like that in the standings, I think Arsenal have to Work a lot more on their way of getting used to winning, that's what they're missing.
Chelsea's loss to Fulham and draw with Everton have really brought bad situation for them. So that they are now at number four in the ranking even I think that next two match of Chelsea easy will gonna be easy because the opponent were the Ipswich Twon and another is Crystal Palace.
Both were the team in English Premier League and that's why I am thinking these two match result could be pushups again above the Arsenal, if Arsenal stay on their current point and as well it is also easy to take back then to second position. Now it remains to be seen if Arsenal draw or lose with Brentford in the upcoming matches and if Nottingham Forest lose the match with Wolves. Although this match will be on January 7, before that Chelsea has the possibility of retaking its place at number two rank imo.
