Ronaldo is hoping for a "dream" farewell when he makes his final appearance for Brazil in the friendly against Romania tonight.
The legendary striker has been handed a swansong performance at the Estadio Pacaembu in Sao Paulo and admits he is desperate to mark the occasion with a goal.
The former Barcelona, Real Madrid, AC Milan and Inter Milan forward said: "I'm very, very nervous and still shocked. It would be a dream if I can score a goal.
"I'm very happy for closing this part of my life with the national team. I have nothing to prove. I only have to thank the Brazilian people for their unconditional support."
Ronaldo, who has played 104 times and scored 67 goals for the Selecao, has been lauded by compatriot Robinho, one of his successors in Mano Menezes' side.
"Ronaldo is my idol," said Robinho. "He has always been. He is a brilliant player and I've watched him since I was a child.
"I'm happy to be part of this event. I was shocked when I was close to him the first time and I am shocked today too."
