Norwich have signed teenager Bali Mumba from Sunderland for an undisclosed fee.
The 18-year-old has signed a four-year deal with the Canaries, who have been relegated from the Premier League.
Mumba, who can play at right-back or in midfield, has been at League One side Sunderland since 2010.
"He's a great lad and full of potential," said Norwich boss Daniel Farke. "We'll give him time to improve and we think we've got a really exciting talent."
