Chelsea had already collected the Under-18 Premier League southern title, Under-18 Premier League Cup and FA Youth Cup before travelling north to Manchester for the national final, which pits the northern and southern winners against each other in a one-off contest.
The Blues not only needed a win to retain their title but also to secure qualification for next season’s UEFA Youth League as domestic champions.
Chelsea U18 defeated United 3-0 to win a fourth consecutive U18 Premier League crown.
Dujon Sterling opened the scoring inside five minutes, a reward for a bright start from the Blues, but Manchester United grew stronger as the half progressed and went in for the break in the ascendancy.
However, two goals after the restart gave Morris’s men one hand on the silverware as Billy Gilmour and then Tariq Lamptey found the back of the net.
Despite a red card shown to Gilmour with a quarter of an hour remaining, the result never seemed in doubt from the moment Lamptey made it 3-0.
