The match between chelsea vs arsenal is very interesting.
Chelsea's current condition is on the rise after some of Potter's schemes were quite successful in the few matches they played but Arsenal is a high wall that must be difficult for Chelsea to pass now.
With the current conditions, this may not be the same as last season where Arsenal can easily beat Chelsea with a striking score but IMO in this match Arsenal are still strong and can get 3 points in this match.
As long as Arsenal can overcome the movement of Sterling on the wing then it will be easier for Arsenal.
First I want to correct the mention of Potter, currently Chelsea is coached by Pochettino, not Potter.
Chelsea's two consecutive wins in the EPL and one win in the EFL in the last three games are good capital when they face Arsenal. Pochettino needs to instruct Chelsea players to play disciplined and close all spaces to make it difficult for Arsenal players to build attacks.
He must realize that Arsenal's strength this season is better than last season. Arsenal's victory over Manchester City has further increased the mentality of Arsenal players to increase their collection of points to reach the top of the standings. There is very little chance for Chelsea to win the match when they host Arsenal, Arsenal's increasingly improving form means that Chelsea must avoid even the slightest mistakes to prevent them from being punished in front of their own supporters.
