Porto president Nuno Pinto da Costa has snapped at reporters asking about the future of Hulk.
The Brazil striker is a top target for Chelsea, though Pinto da Costa insists no concrete offer has yet to arrive for the centre-forward.
"I do not know why you ask me about Hulk and do not ask about Helton or Moutinho, James (Rodriguez), Maicon and all the others. Hulk is not different to any of the others.
"Up to this point there has not been any proposal to FC Porto for Hulk."
