I want to be as optimistic as you are. But to be honest, I don’t really feel at the moment that this season’s Champions League has improved on last season’s.
As you say, Arsenal have strengthened their squad considerably, but they’ve also let some top-class players go, so they’ll need some time to bed in their new signings.
Their next match won’t be particularly difficult for them, and I expect them to beat Lille.
Arsenal wouldn't face any difficulties in the group stage matches because in recent times, they have finished on top of the table of their group. It's from the knockout stage that we might start seeing some laxity in their performance due to fatigue. I don't expect them to be in the finals this season.
Arsenal have started performance have started declining with what they did against Brighton in the premier league today, left everyone speaking because nobody expect a loose from Arsenal against Brighton, with the performance they ended the season with. And
honestly, I also expect Arsenal to win the match, but at the end they couldn't. You said dont expect them to be in the finals which honestly I also start to think same thing, because they already look like they are not ready this season, but we can still watch out and see how the season will go for them.
