Manchester United suffered a 4-0 defeat at Derby County in the opening Under-18 Premier League fixture of the season.
Tom Sang was sent off after the break as the Rams scored twice in each half and also missed a penalty, while the Reds did not get the rub of the green on a couple of occasions.
Luke Thomas gave the Rams the perfect start with an early goal and Cameron Cresswell doubled the lead by capitalising on some confusion in the United defence. A half-time tactical reshuffle and the introduction of Indy Boonen and DJ Buffonge threatened to spark a revival.
