I personally don't think their problem is too far-fetched or exaggerated by the media, even if the media only reports about it once but maybe I personally am one of those people who believe in the problem. The strong reason I believe it is because, Mbappe is still young but PSG gave him some privileges that would at least make this Mbappe stubborn, arrogant or something. So that disharmony in the squad will certainly be easy to happen, moreover the person who is questioned by Mbappe is a senior player who has won more titles than him. This case at least reflects where Mbappe has no respect for older or more senior players, this case is a bad attitude.
The internal conflicts that occur within PSG are delicious food for the media, the media will continue to spread the news as long as there is a clear source.
PSG have made the mistake of giving Mbappe special privileges, the effect is that he is getting bigger with his unprofessional behavior.
Mbappe is increasingly looking more selfish, he feels the player PSG needs the most, Mbappe attitude is increasingly causing cracks in the PSG squad. Christophe Galtier must rebuild harmony between players, if this problem is not resolved immediately, PSG will find it increasingly difficult to get the Champions League Trophy.
