Compared to Luis Enrique and PSG, the Newcastle team and Eddie Howe are inexperienced on a platform like the Champions League. Experience is very important in a competitive platform like the Champions League. Still, it's good that the Newcastle team is performing as it is. I think they will play defensive strategy and try to secure 1 point from the match.
I forgot that Mbappe is going to miss this match. And if Mbappe misses this match, it will be very difficult for PSG to beat the Newcastle side. First of all I would say PSG attack is pretty weak except for Mbappe. The performances of Dembele, Asensio and Ramos have been erratic. On the other hand, Newcastle's defense is very strong. I wouldn't consider PSG as favorites if Mbappe is absent in this match.
I agree but now things are changing drastically before start of this season I was expecting not good about Newcastle United but after watching their performance against AC Milan now I have to change my view about Newcastle United because even they are inexperienced on this platform but still they have done good job and now have good performance against teams like AC Milan and Manchester City we can expect good from them against PSG as well because they are playing at home and having good quality players which can give them good stand.
As of now, it's official Mbappé is going to miss this match surely things are going to be not easy for them because this could be big below, and they have to manage things without him which is surely not easy specially without his presence mostly they fail to give their best specially while we have Newcastle United defence is one of the best right now in Premier League and this could be surely problem for the PSG as well.
