Comparison of the experience factors: PSG is more experienced than Newcastle and PSG's experience is not above AC Milan, but Newcastle is able to predict that bettors will lose money because the result is that AC Milan is unable to beat Newcastle.
In the second match, PSG will have to learn from AC Milan because Newcastle cannot be used as a complementary team in group f. Eddie Howe is not just any coach, he is an intelligent coach who can quickly understand what the team needs to get maximum results.
Playing in front of their own supporters will make a difference for Newcastle in facing PSG.
I can't praise Newcastle too much just because they were able to hold Milan to a draw in their first match in the group stage. In fact, PSG is still a more solid team than Newcastle in Europe even though PSG still failed to win the Champions League title.
Newcastle are slightly more favorites because they are playing at home, but PSG doesn't seem like a random team for Newcastle to beat so easily. Luis Enrique has good experience in the Champions League and that will help him in managing the high pressure of this competition, while Eddie Howe apparently has not. I'm not sure PSG will lose in the second match of the group stage, but I don't rule out that possibility if Newcastle is able to exploit its home advantage perfectly.
