Spurs have been tracking the Atromitos defender and have now invited him to link-up with their development squad as they train in Portugal.
The Greek club have accepted Tottenham's approach and the 17-year-old has now flown out to join the North London club.
Greece youth international Kantoutsis will stay with Spurs in Portugal until 20 July.
And if he impresses enough he will continue his trial in England at the end of the month with a view to sealing a move to White Hart Lane.
