Manchester United boss Erik ten Hag says their youngsters will get a chance if they're good enough.
Hannibal Mejbri has impressed over the past week, while Dan Gore made his full debut in the Carabao Cup win against Crystal Palace.
Ten Hag, ahead of meeting Palace in the Premier League this weekend, said: "Depends on their performances, on their levels, if they can show they can contribute to winning team, based on the opportunity and you win games.
"You've seen already, when you develop players you see the progress and that can help you in tough situations, it's good for the club to develop such players and to get them into professional football and professional top football.
"I like to develop young players but the mentality has to be right and every time you have to prove it and every occasion in training and show it in the games."
