FC Porto will reportedly have to lower their asking price of €70m (£56m) if they want to sell Brazilian forward Hulk.
A number of clubs are said to be interested in the left-footed frontman, including Champions League winners Chelsea.
ESPN quote a source as saying: "Porto's asking price of €70m is simply unrealistic. They might take €60m (£48m), although again that is far, far too high.
"There are many clubs interested, but none at that price, and there will not be a move this summer unless Porto are more realistic.
"It is clear the player wants a move, and Porto are willing to sell but they have refused to be flexible and won't as yet negotiate the transfer valuation."
Despite this, the 25-year-old has recently said that he is in no rush to leave the Portuguese club.
