Neymar is a really great player, as is Mbappe, but their vanities are huge and it is obvious that the PSG team can't have two leaders.
PSG tried to elegantly solve this problem and get rid of Neymar, but they failed because other clubs know very well what they get with Neymar, as an additional package.
PSG has a great and very expensive team, but if they don't solve the problem between Mbappe and Neymar, they won't fulfill their main goal again, winning the Champions League.
I didn't expect this level of show of superiority between Mbappe and Neymar. Before Mbappe made his world record signing with PSG, Neymar used to be the boss and I could say Neymar also contributed in one way or the other to Mbappe speedy development. The hand of the clock shouldn't change so fast. Even if it has to change, for both to understand that Messi who is greater than both is in the club and calm should give a real definition of a star to Mbappe.
