It really depends on the criteria you are using, but there is some merit in asking this question.
Besides Giggs, initially I wasn't that impressed by most of the class of '92. My overriding feeling going into 1995/96 was fear. We'd sold Ince, Hughes and Kanchelskis and replaced them with kids, kids who lost 3-1 to Villa on the first day of the season. My abiding memory of that season was that, while the kids were pretty good, they weren't unbelievably good. To me, Gary Neville was the best of them by far, and I was chuffed when we bought Karel Poborsky after that chip he scored at Old Trafford. I thought he'd be our new right winger, it never once occurred to me that Beckham might become what he did.
Rashford may stand out more because, as a whole, we are operating at a lower level. In 1995/96 Cantona was the star attraction, Keane was coming into his own and Big Pete was still proving to be a wall in tight matches. When Rashford broke into our team our desperation levels were higher, we had no figures like Cantona, Keano and Schmeikes to look to, so maybe that he stood out more? Still, for a kid to be winning Manchester derbies and scoring three minutes into his England début. A pretty electric start. I could get on board with this.
PS) Adnan was a surprising bonus in a terrible, terrible season but I don't think his impact has been what Rashford's has.
