#3 Their quality
With young players who produce performances that defy their age, it is often necessary to remind oneself not to judge them on a level footing with senior accomplished players. Raheem Sterling, Dele Alli, Martial, Rashford et al produce such quality on display almost on a weekly basis that it can be easy to take them for granted.
Young players are often prone to fizzling out after a breakthrough season – but Martial and Rashford have proven themselves beyond doubt with their ability to make it out of a bad patch.
Make no mistake, Rashford and Martial represent United's future not just because of their age and sentimental value. Their quality is right up there with the very best the league has to offer.
Ibrahimovic may have featured more often and taken all the plaudits, but that should take nothing away from these youngsters, whose contribution has been absolutely vital to United' season and will continue to be for several years to come.
