PSG had plenty of chances to take the lead against Bayern Munich, which actually didn't play well at all. De Ligt's role was especially important, he removed a ball on the line. Otherwise it would have become 0-1 and then you get a completely different game. Then PSG would have really had a great chance to progress. It was of course the cracker of the eighth finals, and the fact is that PSG again failed to win the CL. Would players still want to stay? You have stars in this team but no star team. Real Madrid could also go far, but the draw is after the next round next week.
I agree that Bayern Munich was not as dominate as the end result may suggest but i also don't think that PSG really had plenty of chances to take the lead. They maybe had 2 chances to score in the first half and the biggest one of those was after that huge mistake of Bayerns goalkeeper but, as you already said, De Ligt saved the ball from the line.
In the second half though Bayern was the better team and if we are looking at both games, then i think it was completely deserved that Bayern Munich advanced into the next round.
This is another huge blow for Paris Saint Germain and i think it is possible that this is the end of that big star team. Messi does not want to stay, Mbappe also wants to leave probably and PSG already wanted to sell Neymar before the start of this season.
