There was a small window of opportunity for them when they played the Champions League final against Bayern Munich and lost it 0-1. In that game PSG had their chances and they could have won the game with a higher level of efficiency, but Bayern Munich was the team that turned one of their two shots on target into a goal. It was a close game and nobody would have complained if PSG won the final back then.
But the real problem now is that I think PSG is much weaker than they were back then. That's why I highly doubt they can make it into the final again and then win the final. However, if they get some lucky draws now, I don't know maybe they can advance a few rounds. But if they are playing against Manchester City or Bayern Munich or Real Madrid, I can't see how they would be able to beat them.
That's right, because it's impossible for luck to follow them over and over again by getting an easy draw. Moreover, in the quarter-finals and semifinals, what remains are teams that have strong enough strength so it will definitely be very difficult for PSG to compete and win.
I saw this and it is very realistic in my opinion that many people doubt PSG this season because in terms of strength the PSG team is not very strong this season (compared to last season) and they are also often inconsistent.
