Real Madrid on Friday officially unveiled Vinícius José Paixão de Oliveira Júnior.
Vinicius was signed two years ago from Flamengo for 45 million euros ($52.68M), in a deal that would become official after his 18th birthday on July 12, 2018.
The transfer makes him the most expensive in teenager, ahead of Anthony Martial who cost Manchester United £36 million in 2015.
“This is the best opportunity a football player could have.
“I’m going to sacrifice a lot to show that I deserve this opportunity,” he said at his presentation alongside Madrid president Florentino Perez.
“Even at this age (18) I’ll show the coach and my teammates that I’m ready to play, ready to do whatever is necessary,” Vinicius told the media at his unveiling.
