The question mark now is whether Mbappe will really move to Madrid and whether Madrid needs Mbappe, whereas as we can see at the moment Madrid looks quite good, even though they are still lacking several players on the front line as strikers, but to be honest, I'm still not sure about Mbappe. will move there, even though he might move to Madrid, his attitude will definitely change there because he won't feel special anymore like at PSG.
Mbappe's movement to Real Madrid will be subjected to his attitude and Madrid's management decision because if we remember, the management were angry at the player during the transfer summer because he gave the hope of joining them, but letter disappoint them; but since the management are after the strength of the squad, I think the can still accept him for betterment of the team because he is a world class player.
He will not be a special player in Real Madrid's team because the team have important players, so he will not be a special player in the squad, only his performance will give him good recognition.
I also want to see how Mbappe can perform in Laliga apart from Ligue 1 which will definitely take time to adapt again because of the differences in leagues and ways of playing, but whatever it is, I'm still not sure he will really move to Madrid because the news often appears on the surface and It's just a rumor that never comes true, and besides, PSG without Mbappe seems hard to imagine
He will adapt to Laliga's style of play because the Leagues have similar features, and provided he is a world class winger, he will not have any problem and will adapt quickly to the team playing pattern since their pattern is similar to PSG's pattern.
PSG will have to suffer for a while before they can get perfect replacement for Mbappe if they sold him out to Real Madrid, even though it is not yet certain.
