Chelsea are on alert after the agent of Hulk confirmed the Porto striker wants to secure a move to the Premier League this summer.
Chelsea are widely seen as favourites to sign the Brazil international during the summer transfer window, but it is thought they are unwilling to meet Porto's valuation.
Hulk has a €100million buy-out clause in his contract at the Estadio do Dragao and it is thought Porto are unwilling to let him leave the club for less than €40m.
Agent Teodoro Fonseca has already confirmed Chelsea and Paris Saint-Germain are keen on signing his client, while Tottenham are also believed to be showing interest following the appointment of former Chelsea and Porto boss Andre Villas-Boas as their new manager.
And Fonseca has revealed his client is now ready to quit Porto and seek a move to England to help boost his chances of playing for Brazil at the 2014 World Cup.
"Hulk is among the most coveted players in Europe," said Fonseca.
"He feels good at Porto, he is part of the family, but a departure is not impossible.
"He wants to play at the 2014 World Cup in his homeland and playing in England makes this more realistic."
Hulk will be in London later this month as part of Brazil's squad for the 2012 Olympic Games.
