I believe Arsenal can go further in the Champions League and also try as hard as possible in the Premier League, the most important thing is that Mikel Arteta can always overcome existing mistakes without having to feel pressured because Manchester City will always remain their main competitor. I have seen in the last 2 seasons actually Manchester City is not much different from Arsenal, as long as this club remains focused, then they can break Man City's dominance.
Many have high hopes for Arsenal, you also have to consider that many teams have strengthened a lot, I like the way Arsenal plays, I just hope that this season they are more consistent in their games and win more, because sometimes they explode with genius and win games that are very difficult, making it clear that they are very strong, but suddenly they lose against a team that is not doing very well in the PL, and that is already disconcerting, I think that if they correct that, they could even be fighting for 1st place, let us remember how City and Liverpool are doing, they are teams that go with everything.
Arsenal has almost reached the highest level since being handled by Arteta, but their inconsistency towards the end of the season means they always fail to achieve success. Several players need to be brought in to increase their strength, last season Arsenal's front line had a bit of a problem because they had difficulty scoring goals in several matches. Arsenal must appear more consistent to compete in the UCL, they must close all gaps and help each other to achieve victory.
The strength in the defense line needs to be increased so that they don't concede goals easily, Arteta needs to choose players who are able to maintain their best performance to make it difficult for opposing players to penetrate Arsenal defense. Arsenal will be a dark horse team that is ready to surprise, last season Dortmund managed to surprise everyone with its impressive performance, maybe this season Arsenal will start something new that can increase the players' confidence.
