Ney Franco's men reached the final of the competition on Wednesday in defeating Mexico 2-0 courtesy of a second-half double from Henrique.
Brazil will be hoping to pick up their fifth U20 world title, with Uvini desperate to captain his nation to success.
"I feel very proud to be the captain of this team and naturally I'm hoping to win the title. I want to be the one who lifts the cup for the fifth time for Brazil," the Sao Paulo man told Fifa.com.
"This is a dream for me. My aim was to reach the final but it hasn't sunk in yet. It's going to take a while for me to take it all in, and although we still have a big step to take, it would be beautiful to finish it all off by winning the title."
Urging his son on will be Uvini Senior, who the imposing youngster says he owes his career to.
"He's my advisor and best friend. I owe most of my success to him," said the 20-year-old.
"[I'll dedicate victory] to my mother and him, who mean more to me than anything else. I've got their names written on my boots, which says it all. I want to go down in the country's football history and dedicate our fifth U20 World Cup title to them."
Uvini will lead his team out on Saturday evening at El Campin in Bogota in a repeat of the 1991 final, which ended 0-0 with Portgal winning 4-2 on penalties.
