I also see Arsenal as a team that can still be quite strong next season so that some of their closest rivals last season also still have to be wary of Arsenal as their competitor in the race for the Premier League trophy. Likewise in the Champions League because Arsenal could perform better next season and be able to reach a quite crucial stage so that their rivals will still see Arsenal as an opponent that needs to be eliminated early before heading to the quite crucial stages in the Champions League.
These expectations are very similar to what we expected last season but in the end Arsenal were nothing more than a mediocre team in the Champions League competition. They didn't have the conditions to get close to the semifinals and instead they had to fall after successfully qualifying from the group stages.
I don't think any team is afraid or worried about Arsenal's presence and in fact other strong teams are wary of teams full of history who have always been regular champions of the league. Maybe Arsenal is very scary for any team in the same group but after that they are nothing more than a team that can be knocked out easily.
Arsenal's performance has improved and that must be recognized because after all, by looking at the current conditions, Arsenal's performance has been much better, especially in the last 2 seasons. It's just that when they are in the Champions League they will seem the same because after all the Champions League is a condition where the championship club in between domestic leagues gather so that even though their performance has improved but there are other clubs in other competitions also doing that which makes Arsenal still seem to be ordinary. Moreover, with some big clubs subscribing to the Champions League that are equally good, it is clear that they already have special privileges with experience and mentality.
Arsenal can still compete it is a certainty, but when talking about the trophy in the Champions League it will still be very difficult for them to do.
In addition, this season we will see a new draft for the Champions League and of course there will be a lot of different conditions where in addition to the current schedule is definitely increasing, this also makes a club have to be smart to rotate players so that the performance they have in the Champions League with domestic competitions in their respective leagues can be balanced and sometimes problems like this are difficult for Arteta to avoid because they are not the best.
