Rösler was sacked from the position as Lillestrom coach, the club Koren currently plays for, a couple of weeks ago.
The 25-year-old will be available on a Bosman transfer in January, if he fails to agree a new deal with Lillestrom.
Rösler told Stavanger Aftenblad: “Koren is a very good player, that I really like. It’s therefor naturally that I will have a chat with him, regarding his future.”
