Tbh if you saw Rashford play at kids' level there was no comparison. Kelechi in his brief spell at the academy was on another level entirely as a footballer & Rashford was a kid who would not have been sure of a place in any of City's sides at any age group as he came through.
It's the same with most of the kids who have come through to play for Utd. They were not better or in many cases as good as their direct counterparts at City. The biggest difference is that they were being prepared to play whereas ours were being prepared to watch them play.
No way would you have swapped Barker, Ambrose, Boadu etc for Rashford.
Kelechi looked on another planet in comparison & I suspect that will probably end up being the case long term, but tbf to Rashford, some kids do go up several levels when they get time in the first team & surprise/shock everyone.
Something many on here who defend Pellegrini are completely ignorant about regarding developing young players.
The thing about Kelechi, is that what we are seeing now, is the tip of the iceberg. The goals are a kind of bonus talent but not necessarily his main talent. He startrd to show a bit yesterday, dropping deep, playing passes, beating players. That's the part of his game which would have been developed at first team level this season by a proper manager.
The power in the shot, the run from deep. All this stuff is Kelechi. Not a tap in scorer. He'a a No 10 who can run & pass & dribble, shoot etc and may be as good or better at it than KDB once he gets enough games. Even Manuel has mentioned this ability.
Rashford is what we see now. Kelechi is just warming up.
