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.
To be able to win the Champions League trophy is not an easy job, let alone Arsenal, even PSG are still unable to do it. We realize that every team has the opportunity to win the Champions League trophy, including Arsenal, but it is better for them to focus on the Premier League first. In my opinion, Arsenal will have the opportunity to compete with the Champions League favorites in the future, once they are truly able to conquer the Premier League. Arsenal has shown signs of success, Arteta needs to maintain his squad performance so that it does not decline, and start next season more impressively.
We all know that reaching Champions League is another level. It would take so much effort, training, resources, coaching before a certain team can compete on this level. However, it is not impossible to do so. Hard work and perseverance are just couple of vital traits that a Team can have in order to achieve such level.
