The powerful forward is determined to help the Selecao in London and silence the critics regarding his selection in Mano Menezes' squad for the tournament
Selecao legend Romario last week criticised Mano Menezes' 18-man party for the tournament, as he felt that using one of the places for a player over 23 years of age was a mistake.
In his initial reaction to those comments, Hulk demanded respect from Romario, but in a second response to the former striker, he has now declared that his quality is well documented.
"Everyone has their own opinion," he told reporters. "I admire Romario a lot, he was my idol together with Ronaldo, but I do not have anything to prove to anyone. What I have to do is play football.
"This is the first time that I join up with the national team in Brazil. I am happy. The fans' support is impressive. I am ready to help."
Brazil will take on Egypt, Belarus and New Zealand at the Olympics, with their first match scheduled for July 26, against the North African side.
