I agree it looks like Mbappe is more adaptable to Real Madrid, but the chances of signing Mbappe are very small.
Even if it is a small chance, it is not impossible.
We know Mbappe wants to go to a big club like Real Madrid. He also can make another history in the number of transfer fees if he moves. Real Madrid should spend a lot of money if they are really serious to sign Mbappe.
Spending a ton of money for a player is not really a priority for many teams right now because they didn't made a good profit (and most of them lost a great deal) because of the pandemic. It means transfers like Mbappe is a pipe dream by the fans right now, not that it can't be done, it could have been done right now as we speak if we never had pandemic, but because of lack of funding it is harder right now and that is why I do not think that it could be done that easily.
This is why I believe there is a good chance no team makes any transfers above 100+ million levels (which mbappe would have been very easily), there is an exception for Chelsea which can buy Haaland if Dortmund agrees to sell, but that is only because they are the team that won the most, 4th in premier league, finalist in fa cup, winner of ucl, all of those equals a ton of money.
