Now the important thing is what Real Madrid will do with Mbappe as of now. He started badly in a couple of games but later scored multiples goals in one game. Hopefully he will adapt fully without taking too much time.
The problem they are going to have in that team is positioning, we all know the Mbappe is more comfortable when he plays on the left side of attack, rather than in the middle, he is definitely not a striker. Now in Real Madrid, Vini Jr plays from the left, and IMO, he is the best player in the world in that LWF position, so that leaves Mbappe coming from the middle. I don't think Mbappe would flourish from the middle and if he does not, with time there could be disagreements which might affect the team.
I think Mbappé is a player who is open to innovation. I don't think I need to say that he is also very talented. Ancelotti can turn him into very good positions. He can give him new positions. Just like Bellingham. Jude Bellingham has adapted very well to the number 10 position. Mbappé can experience something similar
