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.
Yes Chelsea have really done well in their recent games this season but it will be very difficult for them to win arsenal. Arsenal is in a good firm and dangerous this season. Arsenal meeting with Chelsea is an important game to arsenal that if winning it will lead them having more points and to be at the top of the game, so I don't think this will be a game arsenal would want to lose. It will be Interesting seeing Chelsea performing with their new quality but may not be possible for them to win.
