The Canaries have made it clear that they are in need of another forward, with Jamie Mackie, Danny Graham and Gary Hooper all names linked with a move to Carrow Road.
However, they have now appeared to have turned their attention to the Dutchman and are rumoured to have already seen a £7m bid for the 24-year-old rejected, with Sporting keen on receiving £12m for the player.
Despite his expensive price tag, Hughton admits that his side are exploring the possibilities of signing Van Wolfswinkel.
"Yes, I have seen those reports on him and there is an interest from ourselves but how far that interest has gone from us I don't know," said Hughton.
"But certainly there is an interest."
