Arsenal are good and playing well they just needs more blending because of some new players that joined but in no time they will be fully ready. I like their playing style and mentality, they always want to win matches no matter what and thats what a team needs. I believe in them to challenge and go far in the competition.
I don't think blending is much of the problem Arsenal has got at this time, after all since this. Season they have been blending in so we'll with their performance and Al the team members have had a very even chemistry which has been obvious a few times in their results so I'm not of the opinion that blending is a challenge to them.
They just need to strengthen their attacking and striking force through the next transfer window because currently it's looking like parte isn't functional well enough as expected of him and much pressure is now on Saka to deliver but Declan Rice is still optimal, these few adjustments need to be done before their next UCL fixture if they must be able to deliver through moreover so far they don't really look promising with the champions league except the premier league maybe.
