Mbappe is yet determining his future. This guy keep delay to release his final statement regarding the future of him in the club. PSG is willing to extend him but not even a single word has come from him.
I believe he already decided it and only very big improvements in PSG like they suddenly win Champions League in this season, will be convincing enough to make Mbappe changing his initial plan. Because winning Champions League is what he is chasing for, it is his ambitious plan and he knows at both PSG and Real Madrid, they will give him very good salary offers. What he is considering is at what club, he will be able to win big titles like Champions League and Ballon d'Or.
Mbappe needs to make an official press release to told public regarding the decision on his future.
He will not do it as it is not his style and he did not say anything about his future in the last three seasons. It is a wise strategy from Mbappe because he knows he will create more pressure on both PSG and Real Madrid by keeping silently.
