Neymar won first Libertadores since Pele at Santos, won a treble at Barca and dominated French football with Paris (yeah, not a great feat I know but still)
He also was the most crucial player for getting PSG to the final in 2020, easily best in that campaign
In Brazil he won Confederations Cup, often underrated achievement which was significantly harder than a Copa for example would be. Plus he mostly played with some of the worst selecao lineups ever in the world cup and still managed to put some very good campaigns
I wouldn't attribute Neymar's relative lack of success to his playstyle, there are more things to look for here and they make more sense
Hence, I'm not really worried Lamine might cost us winning more trophies in the future (as obvious as it may sound, he is our best player already and is going to improve more over the years. Well some clearly don't get it)
