Arsenal have only the Premier League left now. They have been eliminated from the EFL Cup and FA Cup so far. And their goal must be qualifying for the Champions League. They are strong enough to make it actually but they have really tough rivals aiming the same thing now. Hence, they will have to focus on playing more effective than them to achieve their goal. Arsenal are having a much greater season than the previous one now. They should be able to benefit from it somehow or it would really be a big disappointment for them after bringing the things here by fighting hard.
I would say Arsenal are not doing anything spectacular this season. I mean, they play and play, they don't make any noise in public and they don't produce any furore. Maybe that's good for them and in that way without the psychological pressure from the crowd they will achieve a result - getting into the Champions League, but I also can't say that this season they are playing weak, very well.
Arsenal's focus should mainly be on how to make It to the Champions League next season. Although, they are presently at the 6th place, which means they have to secure more points in order to slide up on the standings. However, I was expecting Arsenal to probably sign a good striker as an replacement after loaning out Aubameyang to Barcelona to strengthen their squad. But unfortunately they didn't sign any player. And this might affect their performance.
