I don't get the hate in here. He's clearly developed as a character and presented himself as a fair sportsman. No antics, no rolling around unnecessarily, congratulated the Bayern players. Was very professional in the preparation as it seems and his reaction showed how serious he took the tournament.
That being said, he has lots of work to do I think. He got into a tunnel and tried everything by himself, often overseeing the easy passing option. Far too often Mbappe and Neymar got into dribblings in rather harmless positions. It was hard against the pressure Bayern put onto them but still, you can't rush the build up or they'll dominate you.
Individually, he may very well be the best in the world right now. Not sure if he's surpassed Messi already but this CL campaign was great. And he also showed glimpses of that against Bayern when he cut through half der defense and midfield alone. But PSG has to improve as a team in this regard if they want to mess with the very best.
