Djed Spence has completed his move to Tottenham Hotspur.
The 21-year-old’s switch was finalised on Tuesday morning after he underwent a medical at the end of last week.
The right-sided player joined Boro in 2018 from Fulham and made 70 appearances for the club.
Newly capped England U21 international Spence was at Nottingham Forest on loan last season where he made 46 appearances.
