The powerful striker's representative has cast further doubt over the player's future at the Estadio do Dragao by saying the time has come for his client to move on
The Brazil international has persistently been linked with a big-money transfer after becoming a key figure at Porto since joining the club from Tokyo Verdy in 2008.
Earlier in the week, he admitted that he would 'happily' leave Porto for a bigger club, and his representative has now declared that his client's spell at the Estadio do Dragao could be coming to an end.
"This is not a matter of whether the transfer is possible or not, I think this is the right moment for it to happen," Theodoro Fonseca told Antena 1.
"Hulk is the most sought-after player in Europe and we will think of everything with our feet on the ground and together with Porto.
"He entered the club through the front door and he has never said that he wanted to leave, so if he has to move on, he will do so through that same door."
The 25-year-old has a staggering €100 million release clause attached to his contract, but Fonseca believes that the player is value for money.
"Hulk is worth many titles and much happiness," he noted. "I think that is priceless."
Chelsea and Paris Saint-Germain have both been credited with an interest in Hulk, who is contracted to Porto until 2016.
