Manchester United have tied down Brandon Williams to a new contract.
The promising teenager was impressive on debut in the Europa League draw with AZ Alkmaar last month.
The new deal will keep him at United until June 2022, with the option to extend for a further year.
Speaking after the AZ result, manager Ole Gunnar Solskjaer was full of praise for the young fullback.
"You won't see a better full debut from a full back anywhere," the Red Devils coach said.
"The boy is just going to improve and improve. He's got the right mentality. I'm very pleased for him."
