The Feyenoord coach is interested in the Liberty job next season.
Vorm told Voetbal International: "With the Dutch boys, Jonathan de Guzman, Dwight Tiendalli and Marvin Emnes, it is a topic of conversation.
"I think that Koeman has been mentioned in the Dutch media, in particular, as a possible future coach.
"None of the Dutch players has previously worked with Koeman, so at Swansea it remains difficult for us to say anything about it. Though it is clear that he has done a good job at Feyenoord.
"It is a real honour for Swansea that a coach of Ronald Koeman's calibre is interested in managing the club.
"Something like that would have been unthinkable here a few years ago.
"But Garry Monk is a Swansea man, and I think it is important for someone like that to remain tied to the club."
