I think this should be decided soon, as Neymar's relations with PSG are in turmoil and his continuity in Paris seems increasingly uncertain.
Yes, he should leave whenever he gets the chance. It's super difficult to strive in negative-impact environment. With Mbappe move imminent staying back will only cause more damage to his career.
I dont think Neymar should leave Psg anytime soon!!! With Mbappe's transfer now imminent, the No 1 competition neymar has in Psg can be gone!!! and all he has to do is maintain fitness and be the top boy again!! Which is what he has always wanted in his career!!
