Well with what you said because with harmony it will provide a very positive atmosphere and teamwork I'm sure will be created because as happened to some world football players who are arrogant and ostracized by their friends in the club so that ultimately made him unable to work with the team and on the field he could not give his maximum contribution and it was a bad ending for him.
I think there was only a small problem between Neymar and Mbappe last season because Mbappe accused Neymar of his ego on the pitch. After that incident I think they are in good shape, indeed on the one hand if a team has internal problems between players I think it will cause a big problem in the team's journey to win the title because they are not balanced in concentration on the pitch.
Neymar has been closely linked with Chelsea in the past few weeks but until now it seems the rumors have not come true and I think he prefers to stay with PSG this season.
Mbappe should have been sanctioned for bringing such childish behavior to the pitch
Neymar tends to be selfish but why will Mbappe say such outrightly to his face.
The both of them are good they can achieve it all at PSG
