It depends on how Arsenal can improve next season, if they can improve significantly enough then they will be able to go even further in the Champions League. However, on the other hand, if they cannot improve their performance next season, then they will not be able to do much and perhaps qualifying from the group stage will be their achievement, after which they will be eliminated again by the fierce competition in the Champions League.
The team that will join their group is also something that will determine, if they join a relatively easy group, then maybe they will be able to easily qualify for the knockout rounds, but if they join the hell group it will be a challenge for them. But the draw is luck, they definitely hope they can be in a relatively easy group.
Arsenal's performance is unpredictable because they always start the season perfectly, but at the end, they always mess everything up in the Champions League. I can’t confidently say how their performance will be, but I can see that many teams are preparing for the next season, so they can perform very well. I believe Arsenal are also doing the same thing so that they will be a wonder next season.
Although I know that only a few teams will be a challenge for them since they are not, that should be underrated too, but still, Arsenal always end up the season with nothing, which is always a bad result for them. But maybe next season will be a better season for Arsenal, like other seasons have achieved many things before.
This has been the problem with Arsenal, at a time when everyone will trust them to win a title they will begin to drop in performance and even losing matches to lesser clubs and it's very annoying when after winning bigger club they will now bow to smaller teams and this has been a major problem for Arsenal even during the time of Arsene Wenger. Arsenal have made it difficult for people to strongly bank on them to win the champions league due to their previous performances so I don't blame anyone who one who looks down on Arsenal especially within the champions league setting because if they continue this way a time will come when they will be finding it difficult to make it to the champions league because they won't be able to make it to the top 4 positions in the league table.
For so many seasons now Arsenal has not been able to win a major trophy which is a very bad impression for an elite team like Arsenal because England top four teams will be incomplete if Arsenal is not mentioned but I wonder what the problem of the team have been. In the last two seasons they performed extraordinarily well but to win a trophy has became a very big challenge because no matter how strong a team is, the only thing that can crown their efforts is winning a trophy so Arsenal should buckle up now and think about how they can be able to win a major trophy.
