Mbappe is one of the most skilled players at the club so the club will never want to clash with him. What happened when the transfer window opened I think the management forgot about these things, they are only planning for the games ahead and planning to use Mbappe properly as long as he is at the club. Mbappe has contributed to every match PSG has won in Ligue 1 and the Champions League, so there is no doubt that he is the team's most important player. Despite the extension of Mbappe's contract with the club, there are rumors that Mbappe may leave PSG next season.
In my opinion, Mbappe is a player who needs money and is chasing lots of trophies. And he really deserves both. Mbappe is the most frightening striker currently for opposing defenders and goalkeepers, on par with Haaland. Maybe PSG will always have the chance to win the League but what about the Champions League and other prestigious trophies? I think Mbappe will choose to leave PSG in the next transfer market.
