Bellingham, 19, has made the switch to the Bundesliga outfit and follows in the footsteps of his brother, who joined Dortmund from Birmingham City as a 17-year-old in summer 2020.
“Jobe is an exceptionally talented player who, despite his young age, already possesses remarkable maturity and intelligence. We’re convinced that he fits perfectly with our philosophy of promoting young talent and giving them the opportunity to develop at the highest level,” said managing director Lars Ricken.
