Jobe Bellingham has completed a move to Sunderland from Birmingham City for an undisclosed fee.
The precocious 17-year-old midfielder was a regular in John Eustace's squad this season, making 22 appearances in the Championship.
He leaves the Blues at the same age as his brother, Jude Bellingham, did three years ago when he moved to Borussia Dortmund.
And it has become quite the delightful day for the Bellingham family as both Jobe and Jude have completed transfers - the latter finalised his transfer to Real Madrid for an initial £88.
