I'd counted Junior , Vellios, Duffy, and Macaleny as being 21 before the season starts, but they just sneak in, as per the Jan 1st ruling, where players must be U21 before Jan 1st of a season commencing. Junior made it by 17 days, and Vellios by just 7 so don't need to be named in the 25.
*Shane Duffy was actually born on Jan 1st, so could still count as an U21 player this season coming.
