League One club Sunderland have signed defender Dennis Cirkin from Tottenham Hotspur for an undisclosed fee.
The 19-year-old left-back, who did not make a senior appearance for Spurs, has agreed a three-year contract with the Black Cats.
"To get a player of Dennis' quality at 19 speaks wonders in terms of what we're trying to do," Sunderland boss Lee Johnson told the club website.
"He is a top talent and he's very highly regarded within the game."
