Hulk's agent has added fuel to the speculation that the Porto striker could sign for Chelsea this summer.
• Hulk set for Porto exit - agent
Hulk, 25, has been linked with a move away from Porto, with his representative stating earlier this year he has "no doubts" that a deal will be agreed.
Chelsea and Paris St Germain have both been mooted as potential suitors, although his release clause of £80 million could deter interested parties.
Hulk's agent, Teodoro Fonseca, was at Saturday's Champions League final in Munich, and he said: "We are open to talks with Chelsea at any time, any place.
"There is interest, but at the moment there is still nothing concrete. He likes the English Premier League a lot and Chelsea are a good club for Hulk."
