Porto are willing to knockdown Hulk's buyout clause and sell him to Chelsea this summer.
The Telegraph says sources in Portugal suggest Porto are now prepared to re-negotiate Hulk's contract and sell the 25-year-old international this summer for significantly less than the 100 million (£85million) release fee.
But it's now thought, privately, the view has changed after Hulk asked if he could leave and Chelsea followed up an initial inquiry which was met with some encouragement. Up until recently Porto have insisted that the release clause had to be met in full - even if an offer of 99m euros was submitted, according to club president Pinto da Costa - and will publicly continue to maintain that stance.
