Being good in the group stage doesn't mean if PSG will able to pass the play off stage easily. I meant some powerful clubs were getting easier run this season like real madrid and barcelona. These clubs already projected to go to the play off stage easily caused by there was no strong competitor on its group. Real madrid and barcelona were dominating its group as well as the other team like bayern, etc. The play off stage will present several challenges for PSG as they face numerous strong clubs. Winning against dortmund was not enough to be a proof if PSG was strong to face the play off stage.
PSG is not yet safe caused by it's still the first match day of UCL. PSG's position can also be back again to the bottom. I think that the same story will repeat for PSG.
I expect nothing from PSG at this moment. The club was even weaker compared to when neymar and messi were there.
I agree with you, PSG is not safe in the group stage. Winning at home is not enough, at least PSG must get points when playing away while PSG's competitors are strong teams except Newcastle because they are newcomers. Dortmund and Milan are teams that are always there in this phase of course it's not easy to beat them, especially when playing at home, PSG only chance of getting points when playing away is against Newcastle with an additional 1 point is enough.
