Guillermo Varela goal's secured a 3-2 win at Tottenham that sealed the U21 Premier League title for Manchester United.
The result moved United above title rivals Sunderland - who have played all their games - with two games to spare.
United's side boasted a host of names that have been promoted to the first-team fold by Louis van Gaal this season, including Cameron Borthwick-Jackson, Paddy McNair, Donald Love, Andreas Pereira and match-winner Varela.
Defender Love, who has been overlooked by Van Gaal since his breakthrough in February, hammered United ahead inside 10 minutes with his first goal in three-and-a-half years before Varela crossed for Pereira to clinically finish to make it 2-0.
William Miller reduced the arrears for the dominant Tottenham, who were thwarted time and again by the impressive Joel Pereira in the United goal, until Joe Pritchard tapped in from close range after Love, Scott McTominay and Andreas Pereira squandered good openings.
United were not to be outdone, however, with Varela popping up with a fantastic winner to seal Warren Joyce side's third title in four years.
