Newcastle achieved a convincing victory over Chelsea with a score of 4-1, and PSG also achieved a convincing victory 5-2 over Monaco. I really think this is a match that really needs to be avoided if you want to bet, because it is quite difficult to predict, although I understand that PSG has a better hope of securing 3 points.
PSG luck is in the form of squad depth and squad wholeness, and will be playing in front of their own supporters, so Enrique squad will play very comfortably. on the Newcastle side, Eddie Howe had to change his strategy in order to win again like in the first leg, but in reality the injury situation gave him a bit of a headache.
Newcastle victory over Chelsea cannot be completely used as a reference, because The Blues this season are like a club with an acute illness, I mean they are very unstable in the EPL this season. so overall the opportunity for the 4 clubs in group F is still open, even though Newcastle needs a little miracle to qualify for the round of 16.
For me, there are differences between these two teams playing their matches in their respective domestic leagues, but what you say is true, the fact is that both teams beat their opponents with big scores. however, for the Champions League group stage match, it seems that the final result will not be like in the first match when Paris Saint-Germain visited Newcastle's headquarters. like you said, PSG played in front of its own supporters. Likewise, with the depth of the team.
As for Newcastle, their performance is very volatile. the only victory they achieved was when they overthrew PSG at St James' Park, their own headquarters. even so, for me, Enrique really made a blunder with his strategy. apart from that, the problem of injured players was an obstacle for Newcastle when playing against PSG at the Parc des Princes.
Regarding strategy, there are not many changes that Eddie Howe will make. but who knows, maybe in the match against PSG he will do it. or, stick with their signature style of play.
I predict that PSG will win this match, but with the condition that Enrique does not apply the same pattern and rotation as in the first meeting. apart from that, if we refer to the betting bookies, PSG is superior to Newcastle. It's very natural, after all, this match will be held at Paris Saint-Germain's home ground. But what is certain is that we will have to wait until the fifth matchday of the Champions League group phase is held.
