The former Tokyo Verde player has admitted he would find it difficult to resist a transfer to either of the Spanish giants, although he did claim he is happy in Portugal
The Brazilian joined the Portuguese giants from Tokyo Verde in 2008 and has become a star player for his side in recent seasons, earning nine caps for the Brazil national team in the process.
However, despite declaring he is happy where he is, the 25-year-old has admitted he would struggle to resist the temptation of joining either one of the Spanish giants if the opportunity arose.
"I have a lot of affection for Porto but who would not want to play for Barcelona with the quality they have? Barcelona or Real Madrid, I think I would say yes to playing for these teams," the striker told A Bola.
Hulk also admitted he came close to moving to Spain with Atletico Madrid before eventually opting to join Porto.
"At the time I was in Japan I was left to choose between Porto and Atletico Madrid but I preferred Porto because I thought it would be easier to adapt," he added.
"I went to see a Porto game in the old Estadio das Antas and I loved it all, the environment and the fans."
Chelsea have also been linked with the forward but a summer move could prove costly for any suitor with the player having a €100million buyout clause in his contract.
