England under-21 defender Axel Tuanzebe will start for Manchester United in their Europa League group game against Astana at Old Trafford on Thursday,
Tuanzebe has made nine first-team appearances in total for United.
But he has played just one minute in the Premier League this season, coming on as a late substitute in Saturday's narrow 1-0 victory over Leicester.
"It's part of the process of growing. I remember my glimpses in the first team at 19 - it wasn't to be then but now I'm 21 and things are starting to open up more. I know where I want to be going," said Tuanzebe.
Solskjaer added: "If you don't throw them in, you don't know what you've got. I don't see any other way of doing this.
"I've always done it wherever I've been, that's my belief as a coach, to give a chance, an opportunity."
