Axel Tuanzebe has signed a new contract with Manchester United four days after making his first-team debut.
The 19-year-old centre-half, a second-half substitute during Sunday's FA Cup win over Wigan, is now tied to the club until 2020 with the option of a further year's extension.
Tuanzebe has been at United since the age of eight and was last month identified by Jose Mourinho as a real prospect.
Mourinho welcomed the teenager's new deal, saying: "Axel is a young player with great potential. We brought him up to the first team to give him more experience and he has adapted really well.."
Tuanzebe said: "I have always been a Manchester United supporter so I am naturally delighted to have signed a new contract.
"To make my debut at Old Trafford in the FA Cup was a very proud moment, both for me and for my family. I am learning every day in training and it is also a great experience for me to now train with the first team.
"I would like to thank all of the coaches that I have worked with and I would especially like to thank the manager for giving me my debut for this great club."
