This season is going to be entirely different from the previous one because Arsenal will put in more work for improvement and also keep close sights on major titles. The UEFA Champions League is not for newbies but for elite clubs that have stand their ground and knows basically what they need. Arsenal tried their best but couldn't coupled up with the outstanding performance of the club. It's been outrageous for Mikel Arteta and Gunners perhaps he's one of the promising coach to lift the burden of the club since the departure of Arsene Wenger.
The champions league is still going to elude them if they are not in any way making preparations for it because he competition in thw champions league will be even tough than it has ever been as all other teams are seeing how the preparations by others are intensifying because the champions league as known by everyone is really very competitive. The premier league is too but facing teams like Madrid and other top winners who have emerged from other leagues is something we wouldn't want to even for any reason undermine as it will be to the detriment of the team.
Although Arteta managed to improve the quality and performance of Arsenal, but I think Arsenal did not make the Champion League the main goal. Because anyway, sofar it looks like Arsenal are only focusing on being able to compete well in the race for the Premier League trophy and in fact, other tournaments in domestic competitions are also not very good for Arsenal. Therefore,I consider Arsenal to have the main goal of getting good results only in the Premier League and not having maximum efforts for other competitions.
After all, if it's about the Champion League then of course Arsenal are still very far away from being able to compete to the final match. After all,the competing teams in the Champion League are certainly more difficult, moreover Arsenal also do not have a good squad depth for second-tier players. Thus, it will be very difficult to make player rotations to be able to maintain consistency throughout the season.
