The main objective of the PSG team is to do well in the Champions League. They have been trying this for a long time. But they are not seeing success. Hopefully they will try to revamp the squad this season so that they can get into a good Champions League position.
PSG once had nearly all of the good players they could think of in order to win the Champions League, but they failed and were eliminated at some point. They had Messi, Mbappe, and Neymar in their attack and still couldn't win. I'm not sure how their current squad will perform in the forthcoming Champions League tournament, but I don't think they'll be able to win it without most of their key players they once had before.
Most likely psg didn't have any luck last season in the Champions league because they have a very strong squad but failed to advance to the Champions league final. PSG are a big team who have a pretty strong squad but they don't have the mentality to be champions yet.
Manchester city can be a big obstacle for PSG next season because Manchester city is the strongest candidate besides Real Madrid. Next season some teams from epl return to champions league like manchester united. So there is so much competition that will occur next season in the race for the ucl trophy.
I'm sorry, but in my opinion this season with the mbappe problem, PSG has become weaker than last season, just see that Messi, Sergio Ramos and many others left PSG and it seems that mbappe will remain at PSG but won't be playing, so I see PSG having great difficulties in winning Ligue 1 and if they don't even have the conditions to conquer Ligue 1 then even going through the group stage I doubt very much that PSG will be able to do that, let's look at their friendly matches:
PSG 2 - 0 Le Havre AC
as it was an extremely weak team, PSG had no difficulties in winning the game
PSG 0 - 0 Al - Nassr
as it was a medium opponent they couldn't win the game
PSG 2 - 3 Cerezo osaka
even in the face of a weak opponent they didn't win
let's be frank, without messi, without mbappe PSG is nothing and without a great coach with good experience in the champions league PSG will not pass the group stage in my opinion. while manchester city continues with a good squad and with that will be a strong candidate to win the champions league, but it has the arsenal that is also strong, it has manchester united and bayern if they get kane
