Manchester United have signed England Under-19s defender Ayden Heaven from Arsenal on a four-and-a-half-year contract.
The Red Devils say the 18-year-old, who cost an undisclosed compensation fee, will immediately link up with the first-team squad.
The teenager joined Arsenal as a 13-year-old in 2019 and made his senior debut as a substitute in an EFL Cup win at Preston in October.
“I am incredibly proud to join Manchester United. I’m grateful to everyone who helped make this dream a reality,” he said.
“There is so much that I want to achieve in the game, I’ll be giving everything to continue my development and become the best player that I can be.”
Heaven is the second young player to join United from Arsenal this season after 17-year-old striker Chido Obi-Martin moved north in October.
