The Zenit St Petersburg striker has been the subject of intense transfer speculation in recent months, with AS Monaco also believed to be monitoring the Brazil international's situation.
Jose Mourinho has been credited with an interest in bringing Hulk to Stamford Bridge this summer, as he looks to strengthen his Chelsea attack ahead of the 2013/14 campaign.
Spurs boss Andre Villas-Boas is also keen on being reunited with the former Porto frontman, as he too seeks to add to his forward line at White Hart Lane before the close of the transfer window.
Tottenham are already close to completing a deal for one Brazilian, with Corinthians star Paulinho set to arrive in north London in a £17million deal, and now Villas-Boas wants to follow that up by signing the midfielder's international team-mate.
Hulk only signed for Zenit last September in a whopping £52million deal, and even though he is content playing in the Russian Premier League, he hinted that he would be open to a move to a bigger, more prestigious club.
"Those approaches [by other clubs] do exist. There are clubs interested in me," the 26-year-old told TV Paraiba. "But if I am to move, it has to be to a better place, with a better team in a better competition.
"I will be happy too if I stay. Zenit are a great club."
