Da Costa remains defiant and is calm about Hulk's future at the club, insisting he will only sanction his exit if a club is willing to pay his release clause, which stands at a massive 100million.
"I didn't meet Hulk's agent. Hulk is a player with a buyout fee and if any club want him, they just need to pay that, they don't need to come here," said da Costa.
"Hulk will only leave if it interests both Porto and the player. But so far nothing happened to make me think we'll reach that point.
"Therefore, I expect that for this season Hulk will remain a Porto player."
