Porto president Pinto da Costa has insisted that the Portuguese club have not received any offers for their Brazilian striker Hulk.
Chelsea are understood to be leading the race to sign the 25-year-old, but Da Costa has denied that any contact has been made.
"According to the newspapers, Hulk would be long gone now, but what I can guarantee today is that Porto have not yet received any offers for him," Da Costa told Antena 1.
Hulk's contract with Porto expires in 2016.
