Porto have given Hulk a deadline of Wednesday to decide whether he wants to remain at the Portuguese club.
Hulk is a reported transfer target for a number of clubs and Porto have released a statement admitting that he has offers from two English clubs, believed to be Tottenham and Chelsea, as well as Russian club Zenit St. Petersburg.
The club's press officer, Ahaz Felleger, told Antena 1: "Tuesday or, maximum, Wednesday, there will be a solution. There are three proposals from abroad - two English clubs and Zenit - there are talks with the player and with Porto.
"Staying in Porto is also a real possibility. He is very satisfied and there is no problem."
Earlier this month, Hulk hinted that he would prefer a move to the Premier League.
