Hangeland revealed that Jol had probed him about his international team-mate, fuelling talk that the Dutchman would launch a January bid for the 24-year-old.
Jol said: "Don't forget this boy is playing in Brede's position. He could go to the bench then so I don't think he will like that."
But despite competition from other Premier League clubs, Jol remained tight-lipped on speculation he could move for the Norway ace.
Jol added: "I don't want to talk about targets. It's nice he [Hangeland] said something about a team-mate but you want to keep this information private.
"He was open and honest so we might have to switch to another target now!"
