I think it will be another win for Arsenal. Chelsea's victory in the previous two matches will indeed restore their confidence but the problem is that Arsenal is a team that has not been defeated this season and they have consistent tactics and performance in every match. It is very difficult to predict a team as inconsistent as Chelsea so I think this will be an easy win for Arsenal and widen the gap with City in third place in the standings.
Arsenal is clearly stronger at the moment. they beat Man City, although in the Champions League, Arsenal had a surprising result.
and for Chelsea, this is also a tough match because it could prove the development of Pochettino's squad. because after all Arsenal is not like Burnley and Fullham. Arsenal is a team that has not lost a match this season. a big job for Pochettino in the next match. because after this there are matches against other strong teams that must be prepared too.
