Mbappe will have a good time playing in Madrid, just a few months from now he will be receiving his first ever trophy with the club, the UEFA Super Cup final against Atalanta, a welcoming trophy for the newest striker in Madrid.
Though it's more likely Real Madrid will win the super cuo against Atlanta but i still see it somehow in writing Atalanta off totally from winning that match.
During Mbappe stay in Madrid, he would be sure of winning six good trophies if not more. Madrid method of selecting players is what is keeping them with a good record till now, they don't sign many but the few are just the perfect option to fit the box.
The main reason is because we van say they have the best management, that is Perez, who tries to get a good coaches who knows how to improve players and give them the players they want and who may likely still fit the team even if the coach leaves in the long run.
