Mbappe will get privilege base on his performance and contribution to the Madrid's team but isn't something that will happen immediately but with time and base on his contribution in the club, you can take this part away, basically the fact that when these big name players joined a particular club most of them usually get special treatment from their manager and also further having more influence or say in the team than every other player in their.
Mbappé has paved the way for himself and carved out a niche for himself with his impressive and outstanding performance at the league and national level, this act have given him an edge over a lot of players and the popularity he's gotten over the world today.
Real Madrid saw all the potentials and the performance metrics this guy command and decided to leverage on it for a good deal. I don't think Madrid will stand to lose anything with the calculations they've made on the player, it will definitely be profitable for the club at the end. So, congratulations once more to the Madrid club and fans.
