As a passionate Real Madrid fan who's been closely following the happenings in the club since the Frenchman arrived, I want you to understand that anyone that's suggesting that there's a "bad blood" between Kylian Mbappe and Vinicius Jr are people who people who had such wish in them immediately it was announced that Mbappe will join Real Madrid so they're inciting such narrative just to validate their thoughts.
.both players have a great on-field relationship as they've helped each by providing assists or creating goalscoring opportunities for each other ok several occasions. They're very cool with each other and will do everything possible as a team to help the club achieve her goals.
