Frederik Sorensen looked to be a done deal for Leeds United, but reports from Italy suggest that talks over personal terms have broken down.
The 22-year-old, who can play as a right-back or a centre-back, has been in talks with Leeds for several days after a deal with the Italian champions was agreed.
Leeds owner Massimo Cellino confirmed that the terms of the deal would see Sorensen join on loan for next season for a fee of £500,000 with the option to make the deal permanent for around £3.5 million next summer.
It is being suggested that the lack of an agreement could open the door for another of Sorensen's suitors to step in.
Serie A sides Genoa and Verona are believed to be interested and could make contact to try and wrestle the Dane away from Leeds.
Sorensen is seen as a highly promising prospect for the future having already made a number of appearances in Serie A for Juventus and Bologna.
Leeds will be disappointed to miss out if they can't turn talks around, but Sorensen's salary at Juventus may be beyond the Championship side's reach.
