Agree with you. PSG best era was when they had trio strikers Messi-Neymar-Mbappe. If in that era they couldn't win the trophy, it is more impossible to win it in the current era. We don't forget that they are very difficult to qualify to knock-out round this season. They were almost eliminated in group stage by AC Milan because they have the same total points. How they can win UCL trophy if they were difficult to qualify to the current round? Sure, it seems hard to achieve the semi-final round. Let's hope PSG can win against Real Sociedad first before predicting PSG to be the champion. It Real Sociedad defeats them, there is no way to win UCL trophy for PSG.
Paris Saint Germain stand out this season to become very competitive for the league title but I think its going to be tougher for them because there's presence of other tough clubs in the league. The estimated period for PSG to win the UEFA Champions League title have been long overdue because the necessary players, Leo Messi, Neymar Jr and Kylian Mbappe was the frontline for the team's success but it turns out they couldn't because alot of things restrain them from competing in elite competitions.
