Didn't Poch do that as well though? I remember reading that he wanted the same thing coached from youth to the first team so it made transitioning up a level easier. Don't get me wrong, i'm happy with the direct of the on-field play, new executive team and the ethos through the club but parts have been in sync before
Youth team never played the same way as the first team under Poch.
This is most definitely the first time I remember, off the top of my head, in my 30 years of watching that our youth teams at all levels play the same way, inverted full backs and all.
