Spurs have made their first signing in 18 months and immediately loaned him back to the Championship club for the 2019-20 season.
Tottenham have finally ended their long pursuit of Leeds United teenager Jack Clarke.
Leeds reportedly accepted an offer of around £10million plus add-ons for the 18-year-old winger - who signed a four-year deal with Mauricio Pochettino's Lilywhites, but will return to Elland Road on loan next season.
Clarke made 25 appearances in his breakthrough campaign at the West Yorkshire club under Marcelo Bielsa, scoring twice.
"I'm delighted to join Tottenham and in the short term I'll be giving my all to hopefully help Leeds win promotion," Clarke told the club's official website reported.
Lyon and France midfielder Tanguy Ndombele is tipped to be Spurs' next signing of the transfer window after reports in France suggested that the Ligue 1 side accepted an offer for the midfielder yesterday.
