All eyes were on the 18-year-old as the 'Seleçao' locked horns with Chile and whilst the game ended in a draw, Vinicius turned in a fine individual display bursting at the seams with quality.
Brazil's first and only goal of the game came from the youngster as he sped away from his marker down the left before feeding fellow Real Madrid man Rodrygo to slot home.
A missed penalty was one rather large blot on his copybook, the forward slotting a low effort narrowly wide of the post, but his performance in open play was hugely eye-catching on the whole.
In fact, one passage of play in particular saw the winger slip the ball through the legs of his marker down the left before sending in an inviting no-look cross.
After the game, Vinicius revealed his delight at being a Real Madrid player and insisted he was happy to wait for his chance in the first team.
