Rather than risk losing the Frenchman for nothing to Monaco, Spurs would be paying up for the striker.
The Fulham striker, and namesake of Tottenham's current Belgian midfielder, is a highly coveted player as his contract at Craven Cottage expires in the summer.
The Guardian reported earlier in the week that Fulham had no intention of selling the player - as they felt he was invaluable in regards to their Championship relegation battle.
However Sky Sports then reported that Dembele could be on his way to Spurs for a fee between £4 and £6 million.
Now a Guardian reporter on Twitter has suggested that Spurs are set to win the race for the player for an initial fee of £5 million.
So why would Fulham suddenly decide to sell?
AS Monaco, that's why.
Surely Fulham have now decided to cash in on the player after it emerged this week that Dembele was in advanced talks about a move to Monaco, as reported by ESPN.
That deal would have been a free transfer in the summer, when Dembele's contract runs out in West London. With Monaco being a foreign club Fulham were set to receive no money for the player, but if they sell to Tottenham now they will be fairly compensated.
Spurs fans will be hoping that this deal does go ahead as Dembele is a top talent with a bright future in the game. As for Fulham fans, they should be pleased they are at least getting some cash for the player if indeed he does make an exit.
