Manchester United manager Erik ten Hag suggested on Friday he wanted to take a good long look at Kobbie Mainoo before deciding what to do with the youngster this season.
That included giving Mainoo a starting berth in Saturday's 2-0 victory over Arsenal at MetLife Stadium.
The 18-year-old midfielder responded with a mature performance as United took a decisive advantage.
And Ten Hag was delighted.
"Manchester United are known for giving young players chances," said the Dutchman.
"He plays with confidence. I really liked his performance. There are other youngsters with us and they are doing very well."
