Well, one of the things I like about Mbappé is that he is a player who tries to imitate what CR7 did from the beginning. I don't know if you have seen some of his plays, some of the dribbles he does, even the gestures he has, he has always imitated CR7 and it has worked out well for him, so if he has CR7's attitude he can do very well at Madrid. Of course Mbappé has his own style and he himself can make the difference , but the important thing is that he already has a model to follow and that is good I am sure that in that sense he will not fail.
If I'm not mistaken, as far as I know, Mbappe idolizes CR7 because in the video that I saw before, he tried several times to do tricks or games that followed the footsteps of the star player, even with difficult tricks he had tried them. This is actually good, where he himself has good performance and performance with his talent and on the other hand he idolizes a star player who is very experienced in football, this could be one of the things or encouragement for himself, maybe he is very obsessed with football because there is his idol.
By joining Real Madrid, it is actually an opportunity for him to achieve what he has not achieved before, besides that, in my opinion, he has contributed quite well to Real Madrid, with his supportive environment, this makes it easier for him to adapt well.
Apart from that, is Real Madrid currently experiencing problems that make their performance seem to decline, because with last night's match that I saw they lost by a narrow score in the UCL, or maybe they have not shown their best.
