I so much believe in arsenal and the new players they brought to strengthen the squad more knowing that their will be good improvement but looking how the Champions league game will be it will be difficult for arsenal to win champions league. Their are strong teams that will be participating in Premier league and other leagues. I believe arsenal will have a good game in champions league but can't win the league. Manchester City are still the favorite team to win champions league next season.
Hopefully this can be more for them especially by making them one of the most extravagant clubs in the EPL certainly gives more expectations for Arsenal.
But of course the Champions League is not as simple as it seems especially we know Arsenal's problem in full schedule conditions makes Arsenal's performance a little different and a drastic decline in performance always occurs.
Now is an opportunity for Arsenal because they have not been in the Champions League competition for a long time and this can be a new stepping stone for them to be better again to undergo the season both in domestic competitions and in the Champions League competition.
