On the Arsenal side, I have no doubts about the quality and depth of Arteta squad this season, I know the Gunners are unbeaten this season, and even the victory over Man City is still worth celebrating. However, the competition for the top four in the standings will be even more exciting and interesting if Arsenal loses for the first time. For me it's not embarrassing at all to lose to Chelsea, when compared to Wolves victory over Man City.
In my opinion, Chelsea hasn't played well even though they have won twice in a row, but usually Chelsea always surprises them when they meet a top opponent with a favorite club, I'm not sure Chelsea can beat Arsenal, it could be a draw because both of them are equally strong and want victory, Pochettino must organize and pressure Chelsea so as not to lose any more points against Arsenal later.
Playing as hosts, of course Chelsea must be able to hold a draw or get the full three points, as we also know Arsenal are unbeaten in the last five matches but they could get the full three points even though they play as guests, of course they will try to maintain their position in top of the standings and shifting Tottenham also away from Manchester City.
