But Martin insists Juventus have not made an bid for the striker, who will only be allowed to leave Atletico should a club meet the €45million buy-out clause in his contract.
“We received a letter last Monday [from Juventus] and they want to negotiate the transfer of the player. They did not name a figure and we have not provided a response,” Marin told Radio Marca.
“In any case, we will not give any discount in relation to the €45 million clause.”
