Jobe Bellingham has joined Borussia Dortmund from Sunderland on a five-year contract until June 2030.
Sunderland say the fee is a club record, believed to be 32m euros (£26.96m) plus 5m euros (£4.2m) in add-ons.
The 19-year-old midfielder has played for the Black Cats since 2023, making 90 appearances, and helped them secure promotion to the Premier League last season.
Bellingham began his career at Birmingham City, coming through the academy before playing two years of senior football for the club.
Bellingham is following in the footsteps of older brother Jude by moving to the Bundesliga, as the England midfielder – who also came through the Birmingham City youth system – spent three years with Dortmund before joining Real Madrid in 2023.
