There is something more important to this win and that is the margin by which they won. If they end up being equal in points with PSG and they share rank 2 and 3, the direct comparison will decide which team will advance to the next stage in the Champions League and which team will be relegated into the Europa League. Winning 4-1 can be so important because PSG would have to beat Newcastle at least 3-0 to then have the goal difference decide about the order in the table. I think that's one reason why this defeat is really bad for PSG. It raises the pressure even more for the next games.
When your mind and soul is within the game, you will win, not extra work need to be done to achieve that and Newcastle were able to prove that to us. How they confidently played without giving a chance to Mbape need to be study because not a shot on target was allowed by Newcastle center back and I wonder how they will come out of this in their next match against Milan. Even the last time Milan and Newcastle had a friendly match, Milan won by 1 goal to nothing but Mbape wasn't present but what is he going to do with the way he performed yesterday, it's too far from getting that Champions League in PSG, not achievable.
If PSG were to knock off from this group stage, it doesn't mean Europa is secure for them, there is going to be another play off between added spot because there is going to be a limited spot for the qualified participants that made it out for only players that made it out in the third place. PSG is even better compared to other teams in the group for instance look at Dortmund, they are performing better currently sitting in the top four, but I don’t understand why they are slacking in the champions league, their performance was even better last season, as compared to now.
Group F in the champions league is one of the hottest group that is difficult to even discuss about, what result that comes out, I will take it that all the teams in the group have tried all the best because having PSG, Newcastle, Milan, and Dortmund; betting this top four teams is like wasting money because all of them are all good and you don’t know the ones that will end up disappointing you, so I think it’s fair in any of the result that we see.
