The 27-year-old forward is keen to link up with his former Porto boss Andre Villas-Boas at White Hart Lane.
“I learned a lot with Andre Villas-Boas at Porto,” he told in twentyfour7 magazine.
“He is very intelligent tactically. He was almost so well informed about the opponents that we pretty much knew everything about them when we went out on to the pitch.
“It was scary how much we knew.
“I am really happy Villas-Boas is making a mark in England, and it would be fantastic to play under him again one day.”
Hulk is reportedly available for around £25million.
