Tottenham have been given permission to speak to Fulham's Moussa Dembele after the two clubs agreed a fee.
Fulham boss Martin Jol said the 25-year-old Belgium international was having a medical at Tottenham, reports the BBC.
Meanwhile, Fulham are in talks with Kieran Richardson after agreeing a fee for the winger with Sunderland.
Black Cats boss Martin O'Neill confirmed the Wearsiders have accepted an offer for the 27-year-old former Manchester United man.
Dembele, who joined Fulham from Dutch side AZ Alkmaar for £5m in 2010, missed their Capital One Cup defeat at Sheffield Wednesday on Tuesday night.
Spurs' likely capture of the Belgian comes 48 hours after they sanctioned the £30m departure of Croatian midfielder Luka Modric to Real Madrid.
The north London club, under new manager Andre Villas-Boas, have made three signings already this summer, with Emmanuel Adebayor moving from Manchester City for £5m, midfielder Gylfi Sigurdsson joining from Hoffenheim and Jan Vertonghen signing from Ajax.
Meanwhile, Fulham are also doing without the services of American international striker Clint Dempsey, who has not featured in their two Premier League outings to date after telling manager Jol he no longer wanted to play for the club.
Liverpool have expressed an interest in signing the £7.5m-rated forward, but have yet to make a formal offer, and Fulham have reported the Anfield club to the Premier League over their conduct.
