The agent of in-demand frontman Hulk claims Porto remain determined to keep the Brazilian striker out of the clutches of a European rival.
Speculation regarding the Samba star is nothing new, with Porto having had to fend off regular rounds of transfer rumours.
The current window has seen the gossip intensify, though, with Hulk hinting that the time may be right for him to move on.
Chelsea have been monitoring his situation closely, with the Blues known to be long-time admirers of the 25-year-old.
They are said to be planning a big-money approach, with Porto having made it clear that they expect any offer to meet Hulks' buy-out clause.
The Portuguese champions hope that their demands will put potential suitors off, with it their desire to see the highly-rated forward leading their quest for domestic and continental success in 2012/13.
"I've been talking frequently with Porto officials," Hulk's representative Teodoro Fonseca told Record.
"They and their manager count on Hulk and they told me that they want to build a team around Hulk that is capable of winning the Champions League."
