Chelsea target Hulk desperate for London 2012 appearance
Hulk, 25, linked with a host of top European clubs insists he is available, regardless of the hopes of whichever club-side he represents.
The Brazilian forward, who has won his way into Mano Menezes' plans over recent months, believes he can help Brazil towards an elusive Olympic gold medal.
"I'm available to help his team. If coach Mano Menezes calls on me, I will give my maximum," the Porto forward told ESPN Brasil.
"It's always good to be selected for the Seleção. It is always good news and especially now. It's the end of the season and Porto are already champions.
"I thank God that we have had an excellent campaign and that there is space for me in the Seleção.
"I am happy and now it is time to give my all to be among the three players chosen for the Olympic team. And God willing we will bring the title to Brazil.
"Everyone knows the importance of this competition. It is a competition that Brazil has not won and surely this is enough to focus the Selecao on bringing home the title," he added.
