Can't just explain what went wrong with Les Parisiens but it seems that the players are not fit or suffering from fatigue. They were relatively outsmarted and bulldozed by the Newcastle player. I know Mbappe can't wait to leave this club because he needs to chase his dreams somewhere else.
PSG is lack of good players, there are still many mediocre players in their club. Take a look with Newcastle where they don't have any super stars, but all their players are in good quality.
I disagree for Mbappe can't wait to leave PSG, if he want to leave PSG, he wouldn't renew his contract until 2026.
PSG will not able to win Champions League as long as they only focus to sign star players.
