Fulham boss Martin Jol is demanding a contract decision from Brede Hangeland.
Jol is adamant he won't be allowed to follow the likes of Clint Dempsey and Moussa Dembele out of the door.
The Dutchman said: "We will try to do everything that we are capable of to keep him. There is a contract and the only thing for him to do is sign it.
"Players like Brede, if they have a decent history and are playing well for their clubs, then, there will always be an interest.
"I thought he was quite happy to stay here. Of course, he wanted to know the mission of the club - who is coming in because there were quite a lot of players going out.
"There is still five months left and hopefully he will put the money where his mouth is, show everyone he is happy again and sign the contract."
