It has also been reported that Atalanta are interested in Stulac, with Genoa leading the race for the 23-year-old midfielder and having agreed to a deal in principle.
According to the report, Genoa general director Giorgio Perinetti and Giampaolo Marcheggiani originally brought the youngster to Italy for €50,000 (£43,767.51).
Stulac has been playing well for Venezia this season and has been an important player in them finishing in the Serie B playoffs.
According to Transfermarkt.co.uk, the 23-year-old midfielder has scored six goals in 21 Serie B appearances for Venezia this season.
It will be interesting to see what decision the Serie B club and Stulac make regarding his future in the coming days.
Although Genoa are reported to be the favourites, perhaps the lure of playing in England and in front of 30,000 fans at Elland Road could tempt the 23-year-old to switch to Leeds.
