We agree that the 3 clubs AC Milan, Dortmund and Newcastle cannot be underestimated, therefore coach Enrique's demands are very high and as much as possible he does not underestimate the opponents he faces, especially AC Milan and Dortmund, even without Bellingham Dortmund can still give him quite a dangerous game.
With all four clubs in this group, PSG must solve each match especially first matches very well if they don't want to stop this season too early after a group stage.
All three clubs are able to get points or even beat PSG in group matches.
The strength of AC Milan, Dortmund and Newcastle will be a big challenge for PSG to qualify for the last 16, maybe Luis Enrique's troops will lose a few points in their away matches because of the pretty good quality of the opponents. PSG might be able to overcome Newcastle, who has appeared less consistent this season, in the Premier League they have not been able to show their best performance so it is very easy to lose points. PSG must perform optimally if they want to continue their journey to the last 16, they might be able to qualify if they are able to get all the points in the Home match and additional points in the Away match. But I'm not sure PSG will qualify as Group Winners especially as they are in a transitional stage with some new players after their lethal trio broke up.
