The Cottagers centre-back has confirmed that club hierarchy have asked him about the 24-year old who is impressing at club level in his homeland and has already attracted interest from Everton.
"His name has come up," Hangeland told TV2. "They asked me about him after the last international break, so of course I had to be honest and tell them he's a very good footballer.
"It's no wonder Fulham have noticed him, I'm sure he's been noticed by others as well.
"I think it was the manager (Martin Jol) who mentioned it. He picks up on quite a few things.
"He asked me about Forren. I told him that he's a good player, and that occasionally good players come out of Norway as well.
"I try to answer honestly when I'm asked about something. I've often answered that Scandinavian players aren't good enough.
"But when it comes to Vegard Forren, I think he could be good enough for a career abroad. But if it's now or in the future, only time will tell."
