I agree with you. Arsenal first target should be winning Premier League because that will bring a lot more confidence within club and also raise their morale to actually try and win UCL. That's why , next season I do have Arsenal to win Premier League but also reaching at least quarter finals in UCL ( maybe even eliminating Real Madrid ? ) because this club and their players have achieved a level of maturity that can push towards being champions.
Arteta also knows how to keep his players in full focused mode and I'm curious after Euro ends , he will make new transfers because there are some young players who could play for Arsenal this season.

Hold on right there, eliminating Real Madrid?

I think it is way too much. We watched Arsenal in the Champions League. What did they do? They weren't good enough like they were in the Premier League, right? Arteta must be prioritizing a PL trophy for a long time so we don't see the same exact performance in the CL. Otherwise they had quite a big potential there too.
Arteta will go for new signings, yeah. It looks like a top striker is the main target now. Nketiah can't be any use for a team aiming big successes. Gabriel Jesus also isn't like in the past unfortunately.
