Filippo Inzaghi wants to keep on-loan Chelsea midfielder Marco van Ginkel at AC Milan for another season.
Liverpool defender Kolo Toure is close to agreeing an extension to his contract which expires next month.
Centre-back Forren has spent time in Britain already in his career after signing for Southampton in 2013, but he was unable to break into the first team and swiftly headed back to Norway.
Speculation has suggested that he could be a target for Cardiff, who are managed by his former Molde boss Ole Gunnar Solskjaer.
He is not ruling out a move but insists there has been no contact at this stage and he is happy where he is.
"I haven't heard anything serious from Cardiff, but I am ready to listen to offers that come," Forren told VG.
"Otherwise, it is Molde that matters for me."
