It was a very good decision by Mbappe by forcing his way out to seek a better challenge in order to win more trophies. He has served the club well and i believe it was time for them to depart and this is something PSG should understand and move past him, they need to learn to play without certain players and understand that no player will be with them forever. They should start signing players to replace the lost players even though they can’t perfectly fill their void yet.
This is something that every team should be expecting, relying on just one player is not the best thing because one way or the other the player will want to leave when they have a better offer or want to try another league or even in the sooner future the player will reach retirement age. After all the good fortune Messi brought to Barcelona, he left when the time came, same happened to Ronaldo in Real Madrid, so the case of Mbappe shouldn’t be something surprising to Paris-Saint German. Mbappe really played his part well when he was with the team, he has moved on, so should the club also do and look for replacement as soon as possible. His void won’t affect them that much because of the nature of league they’re participating in, not as competitive as other leagues.
They do not rely on him as far as i know. There has not been an excellent result from in a while now who would choose to rely on someone like that. Mbape needs to get out of the club because he is not getting any younger. There are a lot of milestones to achieve and still playing at PSG he wont get other trophies and make big name for himself.
I will agree with you that Mbape literally played his part so well. His team mates were not qualified to work with him because they do not have the same ratings just like him.
