Isn't it interesting that Neymar still doesn't seem to be very friendly to Mbappe now? I'm saying this taking a video related to this into account. As you must have also seen it already Neymar didn't seem eager to work closely with Mbappe and waited for Messi to team up with him. This makes me think about if there is a problem that we don't know currently. I hope that it isn't the case while PSG are trying this hard to win the Champions League especially. The trio must show their best effort this season to have a bigger chance.
Disunity among the players at PSG,especially Neymar and Mbape will not take them anywhere. They've been doing bad lately,not been able to get to the chpuons league final. Neymar is a player that has pride,and there is no way he can stay in thesame team with Mbape because it is obvious to they cannot just play together in peace.
Nevertheless,if they can come together and play together in unity,it is possible that they will win the champions league.
For a long time a number of media have highlighted the conflict between Mbappe and Neymar, especially after PSG extended Mbappe's contract
and in his new contract Mbappe was given considerable authority. This means that it makes Neymar uncomfortable and can also have a bad impact
on Neymar's future. Moreover, Nasser Al-Khelaifi actually really wants Neymar to move to another club and doubts Neymar's future.
The disharmony of Neymar and Mbappe is often seen when they practice together, this can certainly affect PSG's performance.
The problem is that not many big clubs are interested in Neymar, in addition to Neymar's high salary, Neymar is also currently prone to injury.
So it's very small actually Neymar will move to another club, even though PSG are rumored to have included Neymar in the list of players to be sold.
As you said if Neymar and Mbappe could work well together, there is a possibility that PSG could win the Champions League trophy. But unfortunately
until now according to some news that I read, Mbappe and Neymar have not had a good relationship.
