His numbers make it clear that he is among the best players in the world, but he suffers a hard battle in the dressing room. He is only 20-years-old and his coach is determined to make him go slowly, so that he learns what discipline is and so that he isn't so arrogant.
Mbappe, on the other hand, feels like a star, according to 'Mundo Deportivo'. He believes that Tuchel is treating him like a child, because other players who are among the most outstanding on the planet are not substituted. Messi and Cristiano are examples.
The player wants all the minutes he can get and wants to be as important to the team as the perception that he has for himself. His coach prefers that he strengthens himself more and that he bears in mind that he is still learning, both as a footballer and psychologically.
This situation has opened a gap in the club. Leonardo, the club's sporting director, will have to choose between the footballer and the coach in the near future. Their relationship in the dressing room is practically non-existent and there may be changes soon.
