Yes I forgot about them two sorry . And you are right some of next years group were the replacements but will be a year wiser.
Basing my assessment on most recent experiences observing last years u16 absolutely crush the likes of Chelsea with ease and style, then watched U17 group without many of the current crop destroy Blackburn 6-0 this season and looked unplayable on the day.
I read a report in the Athletic about a year ago about playing style and rated players coming through in these age groups and the usuals were in there, but others we have barely seen at U18 so far got notable mentions and the athletic is usually well informed, plus some new signings. All very positive !
