After all, I think the teams in group B, at least it can be said that the teams in group B have a quality that is not much different. Thus, I believe the competition in group B will be very competitive because yes, at least every team in group B both have the chance to get good results. But regarding the match between Arsenal against PSV, at least at this moment Arsenal are still the favored team based on the odds available at this time. But even so, I also think that PSV is not a weak team at all. So, even though Arsenal have a good chance of winning, but it still won't be easy to beat PSV.
I'm sure Arsenal will certainly be optimistic about qualifying for the group without undermining the other contestants in this group, in terms of squad depth, the team's performance in each league. Arsenal is clearly the favorite in this group, but Arsenal is well aware of the many questions, does Arsenal have a European mentality? because playing at UCL is not enough just to have a squad and play well, but you also have to have a European mentality.
If Arteta is able to form that mentality, then winning the group and qualifying is the most likely thing that Arteta and his team can do, plus the fact that it can be a burden and at the same time a motivation for Arteta and his team according to several sources such as ESPN Arsenal are strong candidates to win the UCL this season together. Manchester City, Munich, Madrid and Arsenal.
Again, as I said at the beginning, I'm sure Arsenal are optimistic that this season they can go far in UCL. Of course, it all depends on each club whether they can focus and be consistent or not, especially since the English team has to share focus with the local league, not to mention the problem of injuries.
