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.
Arsenal look more consistent in the Premier League than the Champions League although this is not a true statement.

Yeah... Chelsea have a tough job again after they won 2x even though it is said to be more motivational as many people say, but it is difficult when meeting a team that has not lost they will definitely maintain their record until whatever especially with Chelsea's opponents can be said to be still very unstable against any match so it will be difficult to guess even though I believe in the end it will win is Arsenal.😁
