Is Mbappe too ambitious? Not necessarily.
Mbappe is used to receiving a high salary at PSG, and it's understandable that he might expect a similar sum from Madrid. However, it's important for Madrid to offer what they can afford, without repeating PSG's mistake of offering excessive salaries.
If Mbappe prioritizes money, he may be better off staying at PSG. But if he seeks recognition, then Real Madrid would welcome him.
Negotiations between Real Madrid and Mbappe are natural, and I believe this deal will likely happen at the end of the season.
You can't blame him, he is from France and PSG is an indigenous club of France and it's a honor to play there and having big money is also a blessing because only few of them has such an opportunity. It will be so disappointing if he had left for Real Madrid that time and things doesn't work for him, he will be mock for dispatching his home club for another club and they may not call him for subsequent France national games, there is much that is happening in France that we don't know as fans.
Messi and Neymar were also among the reason why he choose PSG over Real Madrid, Benzema left already only Vinicious and Rodrigo were the ones that put that club on the road after their last UCL but when Neymar and Messi decided to leave the club, that was when PSG and Mbape drama started. To me, he made the decision that favored him and nobody should blame him for that, he has the right because he is still you and talented.
