Hearts are set to sign Liverpool striker Michael Ngoo on loan until the end of the season.
SPL outfit Hearts are under transfer restrictions that stipulate they can only register under-21 players and they have targeted a move for 20-year-old Ngoo.
Hearts boss John McGlynn has already brought in Danny Wilson on a loan from Liverpool and he has raided Anfield again for Ngoo.
Ngoo has yet to make a first-team appearance for Liverpool, but is a regular in the Under 21 side.
Liverpool chief Brendan Rodgers is happy to loan out Ngoo so that he can gain some valuable first-team experience.
Ngoo is expected to go straight into the squad for Saturday's Scottish Communities League Cup semi-final against Inverness.
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.
