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.
Mbappe didn't even need money but he needs to achieve more achievements as many as possible. He never got what he wanted in PSG. This is also the main reason why he was also thinking to leave from PSG instead of stay even longer in the club. Mbappe had no choice other than leave from PSG to develop himself as a great player in this decade. In fact, many people are always supporting him no matter where he will be playing with. Mbapp needs to focus in increasing his experience and quality as a great footballers.
Mbappe has won world cup but he never won UCL trophy. Leaving from PSG will give him the right place to get trophy. I hope he will understand it and try to think about leaving from PSG to join in another club like real madrid.
