The north London club agreed to sell Luka Modric to Real Madrid on Monday, and as such needed a creative midfielder as a replacement.
The Belgium international has grown in stature at Craven Cottage over the last two years, with the likes of Manchester United and Chelsea also touted with interest in the player.
However, Spurs have confirmed that they have sown up a deal for the player to move to White Hart Lane for an undisclosed fee.
“We are delighted to announce that we have reached agreement with Fulham for the transfer of Moussa Dembele,” a club statement on the official website reads.
Dembele has expressed his delight at moving to Andre Villas-Boas’ men and becomes the fourth summer signing after Emmanuel Adebayor, Jan Vertonghen and Gylfi Sigurdsson.
“I’m happy to join Spurs, it’s a fantastic club,” the midfielder admitted.
“You can see over the last few years that Spurs have played well, everybody knows it’s a good team and a good club and that’s why I wanted to come here.
“The club has plans to do lots of good things and that’s why I want to be a part of it,” he concluded.
