It's a good start from PSG while its competitors must get 1 point to draw against each other. PSG has been trying to maximizing the situation. Newcstle and acmilan are draw and it looks like that PSG will not be trying so hard in passing this group.
Mbappe has been doing it so well by scoring against dortmund through penalty. The only dangerous scenario if PSG cannot win against acmilan and newcastle.
It will be a disaster for the club consider newcastle and acmilan are strongest team in this group after PSG. PSG needs to anticipate that.
No need to worry PSG can definitely pass this group phase at least PSG is the 1st or 2nd best club in this group I don't doubt them, the right question is which club will qualify after PSG? there are 3 clubs that will compete for one ticket to the next round Dortmund, Milan or Newcastle and we know that usually Dortmund and Milan always qualify for the next stage but this time we have Newcastle as a newcomer we don't know how their strength.
Newcomers who managed to get 1 point in an away match is a bit encouraging, at least they have opened up hope and will not just be a complementary team, because when they play at home Newcastle will have a greater chance of winning the match against AC Milan.
And PSG succeeding in beating Dortmund at home is according to predictions and agree with you that PSG will qualify from the group phase but who will be with them to play in the knockout phase is still wide open for the other 3 teams.
