Anthony Elanga got to start against Aston Villa in what was his first Premier League start of the season - and only second in his career.
The 19-year-old apparently impressed Manchester United coach Ralf Rangnick.
In tonight's match away against Brentford, the Swede gets new confidence from the start.
Victor Nilsson Lindelöf also starts and United get back the star Cristiano Ronaldo who is ready to play after injury.
After the effort against Aston Villa, Elanga was hailed by Lindelöf.
- He is a great talent who comes here every day and really wants to get better.
He works very, very hard and I am happy for his sake, Lindelöf said to United's website.
The match starts at 21.00.
