Fulham are prepared to sell Moussa Dembele to Tottenham before transfer deadline day and a fee between £4m and £6m could land the striker, Sky sources understand.
And if a deal is struck, it is understood that Spurs would not loan the France U20 back to Craven Cottage for the rest of the season.
Sky sources reported in December that Tottenham were one of a number of clubs from both the Premier League, including Everton, and mainland Europe interested in the 19-year-old, who has scored nine Championship goals this season.
Dembele has just six months left on his contract and his representatives are free to negotiate a pre-contract agreement, with talks having been held with Monaco and Wolfsburg.
But Dembele is one of a number of Tottenham's targets in the current winter window, and the club are currently considering their options with five days left until the deadline on February 1.
Fulham would be due compensation if Dembele leaves the club in the summer instead, agreed either privately or via tribunal, because of the forward's homegrown player status.
But, in that situation, the Whites stand to make less profit on a player they picked up on a free transfer from Paris Saint-Germain in 2013, and the west London club are currently under a transfer embargo.
Dembele is keeping his options open and has been offered a new four-year deal to stay at Craven Cottage, but there remains slim chance he will sign the new terms on offer.
In all competitions, the Frenchman has scored 11 goals in 29 appearances for Fulham this term.
