The agent of star striker Hulk insists his client will not be leaving Porto in the winter transfer window unless it is a 'deal of a lifetime'.
Premier League giants Manchester United, Manchester City, Arsenal and Chelsea have all been linked with the two-time Brazil international and scouts are understood to be monitoring his development.
But his representative, Teodoro Fonseca, is adamant that a January move will only materialise in exceptional circumstances.
Fonseca told Portuguese media: "Hulk will not leave Porto when the market reopens.
"(He will) only move if the club believe that we are facing a deal of lifetime, but our thinking does not entail a transfer at this time.
"Hulk wants to win the title for Porto and the fans."
Fonseca also told Antena 1 of Hulk's contract at Porto: "The termination clause is very high.
"The president [Pinto da Costa] has said he wants to keep him at the club for a long time.
"The biggest clubs in world football are watching. They send observers, but that does not mess with Hulk."
