Manchester United captain Bruno Fernandes praised goalscorers Alejandro Garnacho and Kobbie Mainoo after winning the FA Cup.
Both youngsters impressed for the 2-1 win against Manchester City.
Fernandes said: He's (Mainoo) really good. He's such a such a quality player.
You see the composure that he had in the finishing.
"But part of the DNA of this club is the young players who come through the Academy onto the biggest stage in the world. They showed it again."
