Norwich boss Chris Hughton is in the market for a new striker and has made bids for Celtic's Gary Hooper and Swansea's Danny Graham.
Hughton has been frustrated in his attempts to land either Hooper or Graham and he is now thought to have turned his attentions to Dutch ace van Wolfswinkel.
Van Wolfswinkel has been linked with a move to England and the Premier League for some time with the likes of Tottenham, Liverpool and Newcastle all credited with an interest in the player.
The 23-year-old has impressed for Sporting since his arrival from Fc Utrecht in the summer of 2011.
However, with Sporting struggling in eighth spot in the Portuguese Primera Liga they could face a fight to keep hold of him during this month's transfer window.
Hughton is keen to bring in a proven striker and he is hoping to be given the backing to strike a deal for van Wolfswinkel in what would be a major coup for Norwich.
