PSG's unorganized game made it a little difficult for them, indeed PSG was able to win but in terms of team performance I think they are still lacking and only relying on the trio of Messi, Neymar and also Mbappe is not enough to become a strong team.
PSG's victory was inseparable from the good performance of their front lines, especially the big contribution of Messi, who scored the decisive goal at the end of the game.
The appearance of Mbappe at start helps PSG have more dangerous attacking system and his first goal is very genius moment. He is fast, confident and can not be stopped easily by one or two defenders. The attacking system of PSG will be in trouble with an injury from Neymar and not sure he will recover quick enough to play against Bayern.
Messi did not have a too good match and the late free kick is the only moment I remembered about him in the match. Anyway one moment and he helped PSG to get 3 points.
and if you look at PSG's game I think they have to improve a lot at the back and midfield to face Bayern in the second leg later.
the match against Lille OSC was again an example that their back line and midfield played quite badly, statistically the results of the PSG team's play were only their front line which received a high rating.
Their defense looks really odds and don't deserve very huge money they spent for their defense system. With very unprofessional mistakes, Bayern will be a mountain for PSG to pass through. Bayern won't let PSG to have much ball possession and score goals too easily like Lille.
