Mbappe shouldn't play games with PSG. This is business, if PSG was Mbappe's business, will he want to hire someone,  pay him very huge amount of money as being paid him, then give him other benefits like decision making, because of him they treated Neymar bad and to crown it all, the Champions League he didn't secure foe the club and yet he wants to leave as a free agent. Is that no wickedness?
If Kylian doesn't want to extend his contract, he should be bold enough to say it and PSG will be able to sell him.
Atleast with 150M they can have a good replacement for Mbappe and football continues.
