I think there's no need to discuss about Barcelona vs Napoli and Arsenal vs FC Porto, it's a sure win for both Barcelona and Arsenal, Napoli and FC Porto aren't that good compared to last season.
Arsenal has been inconsistent in the past, which is why there is uncertainty surrounding their ability to defeat Porto. These clubs are equal and it makes sense to talk about them. Additionally, I am concerned about the financial condition of Barcelona because it will have a significant impact on the club's performance.
Barcelona has confirmed to sell some players.
What I think we need to pay attention is PSG vs Real Sociedad and Inter vs Atletico Madrid, I believe most people will think PSG and Inter will win since both of them were strong in the last season, but I believe this time Real Sociedad and Atletico Madrid able to prove themselves even though they're underdog.
Sociedad was as strong as inter. Since last season, Atletico Madrid has opted for minimal changes to its lineup. It seems you are going all in la liga teams right now. I would pick intermilan over atletico madrid.
Im still questioning the performance from sociedad against french club. PSG was strong enough and i think psg has bigger chance to win gainst sociedad.
