The Portuguese club have not offered Hulk a new contract, despite the interest of Chelsea and other leading teams as they have in the past.
“Until now it has not been called for but it is true that Porto always know to reward him," said Teodoro Fonseca.
"The representatives of the club have been kind to him. The president has an unconditional love for Hulk.
“He is a key player at the club and has resisted the calls from the big European clubs in the last three years.”
