WaleedAbbasvD via Reddit: "Damn. Great play from Neymar. Neuer should be keeping that out though. Maybe the ball was too wet?"
FooFighter39 via Reddit: "Reminded me of how Messi pulls away defenders. Even though it may be a mistake from Neuer, credit to Neymar for that perfect pass."
Fati_Future_BallonDor via BarcaForum: "Poor Ney, he won't get Ballon d'Or if PSG wins Champions League, IMO he is better than Mbappe but Mbappe was the only one scoring the goals in the CL."
KingLeo10 via BarcaForum: "Such a force, despite not being in his prime. He had almost everything in his toolkit to be a true all-time great. Which he still might be with a CL with PSG. But still wasted a lot of good years."
