Porto president Pinto da Costa expects
Chelsea target Hulk to remain with the Portuguese club and has claimed that he will not be allowed to leave unless his release clause of €100 million (£78m) is activated.
The 26-year-old scored in Brazil's 2-1 Olympic Games final defeat to Mexico on Saturday and has been strongly linked with a move to Stamford Bridge to replace the recently departed Didier Drogba.
Real Madrid, Paris Saint-Germain and Zenit St Petersburg are also thought to be interested, but now Da Costa has played down the possibility of the striker leaving the Estadio do Dragao.
