The right wing-back, who completed a medical at Hotspur Way on Friday, has signed until June 2027 after Spurs agreed a deal that will see them pay an initial £12.5m, with a further £7.5m coming in performance-related add-ons.
The 21-year-old made 46 appearances on loan for Nottingham Forest last season and there was a chance he might have joined Steve Cooper’s side on a permanent deal this summer.
