PSV Eindhoven forward Steven Bergwijn is set to sign for Tottenham, sources have told ESPN.
Jose Mourinho has been in the market for reinforcements in the January transfer window with Harry Kane ruled out for the forseeable future.
Kane has a hamstring injury and may not be fit until April, leading Mourinho to enter the market to secure a signing in his ongoing absence.
While reports linked Tottenham with Real Sociedad's Willian Jose, sources have told ESPN that the club expect to announce the signing of PSV's Bergwijn instead.
The 22-year-old Netherlands international, capped seven times, has been at PSV since 2011, when he joined their youth set-up from Ajax. He has five goals in 16 league appearances this season.
