The bulk of the 2,129 minutes played by United teenagers this term have been taken by two first-team regulars, who are currently on the sidelines.
Kobbie Mainoo (1,285 minutes) has featured on 18 occasions, although he's missed our last five outings through injury, while Leny Yoro's 700 minutes have been carefully managed after he had foot surgery in the summer.
Amorim will hope the 19-year-olds can be involved again after the international break and, if they do, the Reds could draw closer to Tottenham Hotspur, who lead the way when it comes to this particular stat.
Ange Postecoglou has picked seven different teenagers in the league this season and they've appeared for a combined 2,839 minutes, with Archie Gray (1,245) and Lucas Bergvall (934) playing most often.
